DESCRIPTION Rugged, waterproof, glass lens, 100-277 VAC. This unit is built to last.  Designed to match natural sunlight levels, the FGI UVA LED Grow Light offers extended spectrum Supplemental Blue 340-400 nm with an added PAR Booster to ensure optimal absorption of the light energy. Perfect for indoor growers and plant enthusiasts! The reason for this is that plant morphology is affected by the spectral composition of light, which means that different wavelengths of light can promote different plant growth. In particular, blue light is known to encourage compact growth and strong stems, making it an essential part of plant development. By providing plants with the same level of blue light as they would receive from the sun, the FGI 385nm UV Lightbar ensures that they can grow and develop in the best possible way. As a result, it is an invaluable tool for any gardener or plant lover who wants their plants to thrive. Science behind using UV-A supplemental energy on plants Recent studies at Utah State University have shown that plants absorb and benefit from light between 380-740NM. This research has led to the study of E-PAR or extended PAR and is redefining measurement of photosynthetic light.  Below are the spectrum charts which compare natural sunlight to full spectrum LEDs and then to full spectrum plus supplemental UV.  The result is a closer match to sunlight providing more of the beneficial blue light that plants benefit from.  Sunlight Levels of 380NM UV Natural sunlight provides plants 1.22 umols of 380nm blue energy.  Natural Sunlight Spectrum Blue Energy 1.2234 umols Typical Full Spectrum LED Lack 380NM UV Full spectrum LEDs have limited blue spectrum which peak at 460nm.   Full Spectrum LED 460nm Blue Energy Levels .0514 umols Full Spectrum LED with Supplemental 380NM UV  Adding supplemental 385NM UV creates a secondary peak of blue energy at 1.5047 umols at 12" from the canopy, roughly equaling natural sunlight.  Supplemental UV Spectrum plus Full Spectrum Blue Energy 1.5047 umols (3x greater)  Build Quality These are high quality units with a crystal glass lens cover to protect the diodes and allow for cleaning. The all aluminum frame dissipates what little heat the bar creates. At 30 watts the Lightbar sips energy too.  Spectrum Theory  Blue energy is scientifically known to help form more compact plants. More lush leaf growth, stronger and larger stems and tighter internodal spacing. We gave a prominent researcher at a major State University one our 385NM UVA Lightbars:  "Your UVA lights arrived and we have confirmed their 385 nm peak. This looks like a high quality fixture." He went on to say: "Elevated exposure to UV photons is known to enhance the synthesis of UV blocking compounds in the leaves of many species and it is reasonable to think that UV photons can increase the synthesis of secondary metabolites in plants." And further, "I expect we will find value in dosing of CSat plants with UV photons, but not surprisingly, the effects will likely interact with UV wavelength, intensity, timing of delivery, and growth stage." The UVA Lightbar fits neatly inside the frame of our Uniformity Pro LEDs as well as many other multi-bar style full spectrum LEDs. Use We recommend two of our UV-A LEDs over each 4'x4' area. The slim design allows them to be hung inside the frame of most 6 and 8 bar LEDs. Mounting height should be at the same level to avoid creating shadowing.  Control A basic digital 110V wall timer can be used, or if using the TrolMaster Hydro X we recommend the DSP-1 module for 110V or DSP-2 for 120V power connection and multiple on/off timer programming.   ~Technical Specs~ Product 30W（±5%） 20 UVA Diodes Per Bar 100-277VAC,50/60 Hz 102.3BTU IP65 44.88”x 2.24”x 1.53” 4.4 lbs Photometric File Download Product Warranty (see our warranty here) 3 year warranty

Overview  Rugged, waterproof, glass lens, 100-277 VAC. This unit is built to last.  Our far red lightbar is the most popular 4' long 730nm grow light on the market today. Industrial grade construction. All aluminium housing. Internal LED driver.  About Growing with Far Red Energy Far-red light is good for plant growth. It can increase photosynthesis, enhance growth, and increase plant size. Far-red light is significant to plants because it increases the ability of plants to capture light. Plants use light not only as a source of energy, but also for information about the surrounding environment. Far-red light is typically not absorbed much by plant leaves, and it doesn't drive any photosynthesis because it is mostly reflected off leaves. However, if a plant "senses" a greater ratio of far-red to normal light then it "knows" that obstructions or other plants are close to it. Far-red light can also regulate leaf angle and increase plant height and leaf area, via expression of associated genes, to capture more light energy. The lightbar features a crystal lens that covers the diodes, making it waterproof and resistant to overspray. Additionally, the lightbar is designed to be easily moved and bumped around, making it one of the most versatile and user-friendly grow lights on the market. However, what sets this light apart from others is its ability to stimulate plant morphology. By emitting a high intensity of far red light, the FGI Far Red Lightbar encourages plant growth and development, making it the perfect choice for any serious gardener or farmer. Use far red energy in veg to keep plants compact and strong. Recent studies at Utah State University by Dr Bruce Bugbee, have proven that additional energy, even in the red spectrum, keeps plants more compact.  The science of using far red light on plants Recent studies at the University of Texas El Paso / University of Texas Arlington, concluded that plants exposed to full spectrum plus dosing with far red spectrum, increased overall plant mass/yield and also improved terpene profiles. Read the study here. The light coverage of this product is unmatched. It will fully cover a 4' wide grow tray in bloom and generally covers a 2' wide swath. We recommend a pair for each 4x4 grow space and this unit comes with hardware which allows you to position it inside the frame of most 5 and 8 bar full spectrum LEDs. This light system is one of the best on the market and will give your plants the light they need to thrive. Order now and be sure to get your grow space set up correctly so you can achieve maximum light coverage. Targeting the Emerson Effect. The Emerson Effect is the name given to the increase in the rate of photosynthesis that occurs when chloroplasts are exposed to far red energy just before the nighttime lights off cycle. This effect was first discovered by scientist Alexander Emerson in 1883, and it has since been extensively studied by plant biologists. While the Emerson Effect is typically associated with increases in photosynthesis, it can also lead to other changes in plant physiology, such as increased cell division and growth. One way to take advantage of the Emerson Effect is to use our supplimental far red LED grow light for 10-15 minutes after full spectrum lights are turned off. If you are looking to create the ideal environment for your plants, an LED grow light can help you to achieve the Emerson Effect.   Far Red Spectrum Use We recommend 2 units per 4x4 grow space for daytime enhanced PPFD delivery. Height over canopy should be the same as your full spectrum LED but it will not hurt the plants to hang beneath a 4x4 LED.  Time General use: Studies indicate that dosing with far red light is most effective with 4 hours on, 4 off, and 4 on. We recommend a digital wall timer, or if using TrolMaster the DSP-1 (for 110V connections) or a DSP-2 (for 240V).  Emerson Effect:  10-15 minutes after full spectrum lights are turned off. Plant Morphology Theory Plants use phytochrome to detect and respond to red and far-red wavelengths. Phytochromes are signaling proteins that promote photomorphogenesis in response to red light and far-red light. Phytochrome is the only known photoreceptor that absorbs light in the red/far red spectrum of light (600-750 nm). (source: Wikipedia) Far Red light is believed to create a competitive response in plants, pushing desirable terpene production and assisting in the formation of trichomes.   Read more about Far Red and extended spectrum in this recent release from Design Lights Consortium: Read It Here   ~Technical Specs~ Product 30W（±5%） PPF 72.1 umols/s  100-277VAC,50/60 Hz 102.3BTU IP65 44.88”x 2.24”x 1.53” 4.4 lbs Photometric Test Report Download  Product Warranty (see our warranty here) 3 year warranty

(CO2 recommended for this light level). Or grow at 800 umols/ms without CO2. It can be used for Veg when dimmed. And when fully dimmed can be used over clones and starts too.Below are PAR readings with the lights at three different distances. At 24" expect PPFD to be above 1000 umols/ms, but not as uniform. At 30" PAR will be above 750 umols/ms. This is an ideal light level if not using supplemental CO2. These levels are equal to a typical HPS grow space.At 36" light levels become more uniform from corner to corner but at 680 umols are below what we'd recommend for flower.At 48", light levels are the most uniform and are perfect for mature veg plants. Use the built in dimmer to reduce intensity for young veg plants.

The Hortibest Master Controller helps manage your grow environment by sensing light, temperatur and humidity levels.  Use one or both channels to manage zones.  Programmable sunrise, sunset, on/off and auto temp dimming protects plants from overheating.  The controller uses two sensors to provide redundancy and improve room control. Plug and play, using provided RJ-14 cabling for the factory-direct Hortibest line of LED grow lights.  Master Controller User Manual Download  Hortibest LED Dimming Control Wiring Diagram

The FGI Dimming Controller provides control over one or many LEDs or 0-10V capeable ballasts. Designed to operate lighting over distances up to 100 feet, the FGI Dimming Controller features robust controls to manage your grow room environment. Connect the controller to an entire room and build sunrise, sunset scenarios to gently wake your plants and put them to bed as nature does in the wild. Or manage rooms and connect several Dimming Controllers to manage strain specific rows or vertical racks of LEDs. Automatically assists in room temperature control by dimming down lights if the temperature setting shows the room is too hot. Adjusts light levels back up when the room is within the setting you choose. Set on and off timers and program sunrise and sunset dimming to mimic natural sunlight and get the most out of your plants.  For use with; All 0-10V dimmable LEDs (see your driver specifications) Not for use with our FGI Hortibest Commercial Series LEDs. Please view the Hortibest Master Controller.   All 0-10V controllable lighting (may require custom wiring - or TrolMaster ECS cable kits which can be used universally.) Control one or many lights.  Programmable Sunrise and Sunset Mode. System over temperature protection built in to protect your plants from accidental overheating in your grow space programming auto-dimming to reduce heat output. Attractive and easy to use touchscreen programming. 110V powered with battery backup. This unit is powerful enough to connect properly daisy chained units up to 30 meters from the control module.   Q&A: Is this Controller an On/Off switch? Not with the V1 version however yes with our new V2 version which will dim the Uniformity Pro 320 and Uniformity Pro 640 to off. This controller can be used with LED drivers which have the ability to dim to zero to turn your light off. It will not eliminate power to the light. It will however turn off the diodes if your driver has dim to zero capability.   Can the FGI Dimming Controller operate non-FGI LEDs? Yes, it can operate any LED that has a driver (power supply) that allows zero to ten volt dimming (0-10V). Consult the specifications of your LED light, or the specifications of the driver/power supply in the light itself. Most drivers have labels affixed to them that indicate their ability to do 0-10V dimming. How can I tell if my driver is 0-10V? 1. Look at the specifications for the model number of the driver, usually printed on a label on the driver. 2. Look for an indication on the label that the driver is 0-10V dimmable. 3. Look for a pair of wires on the driver/power supply that are NOT used to provide power to the light. Typically these are blue/black but can be a variety of colors based on the manufacturer. Can I connect the FGI Dimming Controller directly to the line voltage power on the light? No. Do not connect the Controller directly to line voltage power in your LED. It will damage the controller and void the return. Can this controller turn my LED totally off? Yes for the FGI Uniformity Pro series LEDs. No, it cannot dim the FGI Lightpanel or Lightbar products to off. For non FGI LEDs it depends on the driver/power supply. Consult the specifications for your driver. If the driver has the ability to "Dim To Off", then it is likely but not 100% that our Controller can dim your lights to off. Otherwise they will dim to 10% of the total light output only. Can I connect many lights to one controller? And if so how many? This depends on the distance you are trying to connect your lights over and the quality of the wire you use. We recommend insulated AWG 14 2 lead wire sold here on Amazon. And we also recommend you use IP68 twist connectors also sold here on Amazon to create a water proof, dust proof daisy chain. 3 way IP68 T connectors are ideal for this application.

Official authorized distributor of FGI brand products. Exclusively available from Forever Green Indoors.  Note: We have one new 16' lift pre-built and in stock for immediate shipment. 10/2023 Description Lightweight, heavy duty, universal light lifting solution for grow lights.  The FGI motorized light lift is a great tool for managing PAR on canopy. It can raise and lower lights 30 inches to give you an even distribution of brightness, making it perfect whether your plants are close or far away from the source! The universal mounting system allows any brand of lamps to be installed with ease too; so there's no need worry about getting wrong type equipment when trying new techniques at growing indoors. Mount at any distance from ceiling. Upper light lift rail holds twin pnumatic motors activated by an up/down switch. The lower rail holds your lights. Heavy duty steel cable connects the top and bottom rail on a set of pullys coordinated to pull the lower rail up and down.  The lower rail, when fully retracted (pulled all the way up) should be set to where you want the lights at finished canopy height. This would be the same height you'd choose if you did not use a light lift.  30" of travel allows you to drop the lights during the plant strecth phase to increase PAR levels you would otherwise lose by having your lights mounted in a fixed position. Wasted PAR, wasted energy cost. Grow lights lose 50% of their energy over distance. For example if you bought lights to produce 1200 umols/ms at finished canopy height, say 18". Each 12" further away will reduce PAR by 50%. At 24" from the light PAR will drop to 600 umols/ms. At 36" PAR will drop by 50% once again to 300 umols/ms which is less than what Veg plants require, not to mention early flowering plants.  The lightlift gives back wasted PAR and allows growers to concentrate the PPPFD they desire at all stages of growth.   View Customer Installs on Youtube    Introducing the FGI Lightlifer     Seattle Demo Install    ** Due to the size and weight this item does not ship free ** Ships to USA and Canada only ** Shipping calculated at checkout.  Features: Standard lengths: 16' and 24" Standard Unit Weight: 98 and 120 lbs (not including lamps) Input voltage: 110V per section. Lamp mounting: Integrated quick release mounting for FGI's full line of Lightbars and Lightpanels. We can make Lifters for any brand of grow lights. Twin linear actuators raise and lower the array with the toggle switch Capacity: Up to 250 or 310 lbs Standard travel: Up to 30" up/down travel Safety: Handheld (or wall mounted) up/down switch for each lift.  Slow movement with upper limit and lower limit travel stops Secure universal light attachments using 1/4" cotter pins Install Notes: The FGI Lightlifter comes with pre-assembled top rails with pneumatic arms and steel aircraft cable. It ships in 8' sections with joining hardware to extend the final lift to 16'. The lower rails come pre-assembled and we provide sets of clevis cotter pins and rail insertion guides.  The lifts consist of twin upper and lower rails. The upper rail has four loops, one at each end, and allows for attachment to ceiling truss which we recommend be done with lengths of stainless steel threaded rod (not provided). The rod should be sized to allow the upper rail to be suspended at a height for the top limit of travel, or in other words the furthest you want the lights to be from the canopy. The lower rails on the lift hold the lights which have 30" of travel when fully extended. Steel aircraft cable (all parts provided) allows for a strong and safe up/down travel.  Alternatively, the lift can be suspended from the ceiling truss using chain (not provided).  Also recommended for simplifying the truss connection is lengths of Unistrut or Superstrut attached to the ceiling truss. Threaded eye bolts installed on the strut allow for adjustments after the fact.  Lift mounting width: The twin 16' rails are independent of one another. In other words, they do not need to be attached to one another. Each of the two sets of top and bottom lifting rails can be mounted at any distance. This allows the lift to be easily adapted to most brands of grow lights. The rail sets would then be mounted at the same distance that the light mounting points are from one another. This allows the lights to be balanced and properly sized to fit the lifts.  Light attachment: Our lifts were designed for FGI brand grow lights which have flip up brackets sized to fit into the lower lift rails. However in most cases any brand of light can be used with the lifts. Rope hangers or steel loop cables can be used to attach to the provided mounting guide and clevis with cotter pins. Rope hangars and loop cables are not provided.  Clevis cotter pins and rail guides included
