Q: Why should I purchase a Timber DIY kit?
A: DIY Kits enable the grower to customize the placement of the light to accomodate a variety of different configurations. Many sellers also sell kits - these are components that you must assemble. We offer kits that are already pre-wired - these are professionally wired to a Meanwell power supply, with properly grounded connections, and a fused 10A power inlet - for safety. Our kits include all accessories - power cords, reflectors and mounting hardware.
Our kits also come pre-drilled and tapped and are already assembled with (4) mounting holes on the heatsink, designed for easy attachment to the frame of your choice.
For those folks who want safety and convenience, this kit provides top of the line components pre-assembled for safety and ease of installation.
Additionally, all Timber products must pass a stringent testing/QA process prior to shipping.
Q: Which DIY Kit is best for me?
A: We offer kits ranging in power between 100-300 watts. Our kits are designed for maximum efficiency - which is roughly 50W per COB LED. Our kits are available with pre-wired power supplies and dimmers - this includes a 10 amp fused power inlet for safety of operation.
Our kits are drilled and tapped - no need for tools - and are designed to attach to a standard frame. We recommend using aluminum L-channel for low cost and ease of assembly.
Q: What is the difference between the Citizen CLU048-1212, Cree CXB3590 and Vero29 COB LEDs?
A: We offer kits and framework using Cree, Citizen and Bridgelux Vero29 LEDs. With respect to power consumption and PAR output, these are very similar. There are a few differences worth noting:
- Cree does binning - Citizen and Bridgelux do not. Binning is a method of categorizing LEDs by light output (lumens) at the time of manufacturing. We only use top BIN Cree CXB3590 (CD bin) LEDs.
- The Citizen CLU048 COB is physically smaller than the CXB3590 COB - this smaller surface area will have different heat transference characteristics versus a COB with more surface area like the larger CXB3590. That said, we use heatsinks matched to the specifications of each chip in order to ensure that our kits and framework are well within the specifications regarding thermal design.
- The Vero29 COB LEDs are used exclusively in our high output products as they are designed with a higher driver voltage and are the most efficient of the three types when driven above 50 watts/COB.
Q: What color temperature should I choose?
A: Most customers choose the 3500 K color temperature. This color temperature has been proven by growers to produce the best results in flowering cannabis. The 3500 K color spectrum has a good amount of deep red (620-660 nM) which aids in the flowering stage. 3000 K is also very good for flowering with it's enhanced 660 nM spectral output.
4000 K and 5000 K are good for vegging and also has many applications well suited for young plants.
Please contact us with any questions regarding the best color temp for your growing needs.
Q: Can I mix color temps?
A: Sure! We can customize any kit to include the color temps of your choice. If you have specific needs let us know - our COB LEDs are available in 3000K, 3500K, 4000K, 5000K and 6500K color temps. You are welcome to mix and match color temperatures as well - there is no additional charge.
Q: How much is shipping?
A: We ship by USPS Priority Mail and UPS with 3-5 business days service to most of the US. Shipping quotes are available at checkout.
International shipping is available - please contact us at firstname.lastname@example.org for shipping quotes.
Q: What are the coverage area sizes?
A: Coverage areas vary by model - a good general rule of thumb is 35-50W per square foot of coverage area.
Q: Is it hard to assemble a frame?
A: Assembling a frame is easy - we recommend L-Channel aluminum frame, available at your local hardware store or metal supply company. 1" x 1" is a good size and 1/8" thickness will make a very stout frame. Our kits have holes and screws in the top of each heatsink to attach to your frame - all you need to do is assemble the frame and drill the holes to attach to the heatsink and power supply.
Q: What if I don't want to build a frame?
A: No problem - all of our kits are also available pre-assembled on an aluminum frame! These Framework products come pre-assembled and ready to hang and grow with sizes to match your specific coverage area needs. Please contact us at 866-892-5364 or by chat or email and we would be happy to assist with your specific coverage area needs.
Q: What are the coverage area sizes?
A: Coverage areas vary by model - a good general rule of thumb is 35-50W per square foot of coverage area. Feel free to contact us with any questions regarding your specific needs. Customizations are available and rarely are there any additional costs.
Our line of framework is designed to cover most common coverage areas from 1' x 2' up to 5' x 5'. Larger framework can ship disassembled to save money on shipping costs as well.
Q: How high above the plants should I hang my Timber light?
A: All our models are designed to provide uniform intensity and coverage at a height of 12”-18” above the canopy. Additionally, our lights come equipped with dimmers allowing you to adjust the light output and coverage area to suit your individual grow environment. Timber Grow Lights run very cool - cool to the touch - and can be used very close to the canopy.
Q: Where are your fixtures made?
A: Our grow lights are engineered and built in California by lighting professionals. Timber Grow Lights are assembled using top of the line, cutting edge components from Cree, Citizen, Bridgelux, Meanwell, Cooliance and Ledil.
Q: Why LED vs HPS?
A: LEDs compete with traditional HPS and Metal Halide HID lighting sources in a number of ways, including greater energy efficiency, longer lifetime, and smaller size. They, however, are more expensive.
LEDs operate at a much lower temperature so there are less cooling requirements (energy, noisy a/c and fans) – also, because they put out less heat they can be positioned closer to the plant canopy. The ability to configure LEDs also helps to increase their usability over HPS, which traditionally must be positioned higher – and directly above – the canopy. LEDs can be placed in different configurations above the canopy to suit many different sized growing areas.
Dimmers, included in all Timber Grow Lights, enable the grower to power, or down, depending on the stage of growth, DLI requirements, and growing space. There are no costly bulb nor reflector replacements required with Timber LEDs. Plug them in and start to grow.
Q: What are COB LEDs?
A: COB (chip on board) LEDs consist of up to 100 LEDs packaged in a tight bundle to maximize light output from a small area. When spaced appropriately, COBs provide the same coverage as an HPS bulb and generate much less heat and can be adjusted to suit any grow space.
We use Cree CXB3590, Citizen CLU048 and Vero29 COBs exclusively as they most closely mimic the spectral output of the McCree Spectrum. Providing light in all wavelengths between 400-800 nM, instead of just at the Chlorophyll A&B peaks as in red and blue LED fixtures, gives the energy required for all the plant’s physiological responses.
Q: What color temperature should I select?
A: For full cycle growth and flowering, most customers choose the 3500 K color temperature. For vegetative growth and seedlings, we also offer cooler color temperatures such as 4000 K and 5000 K. Many customers also choose to mix 3000 K and 3500 K for full cycle as well.
Q: Why are dimmers used in all Timber Grow Lights?
A: Dimming helps to adjust the power of the light output, allowing for use at varying distances to the canopy, as well as adjusting the area of coverage. This is helpful in height constrained growing environments as well as situations where more PAR intensity is required.
Important to note – dimming the fixture also increases the efficiency. The “softer” the fixture is driven the less amount of heat output and therefore the majority of the energy is converted to photons of light energy to aid the plant in growth.
All Timber Grow lights are able to be dimmed from 10-100% power, allowing maximum control of power and coverage area. This allows the grower master control over the intensity and size of the light beam pattern. Many growers use the dimming function during plant inspection and maintenance.
Q: Why are optics important....or not? Can I run these without optics? If so, what are the benefits/drawbacks?
A: Reflectors and lenses are used to manipulate the light output. Reflectors 'reflect' stray photons of light back to the plant canopy. Think of them as a bumper for the light to bounce off of. We offer LEDIL Angelina high efficiency reflectors with all of our products, designed to provide even light spread over a large area (up to 5'x5' in flower). This allows for a nice even blanket of light across the entire canopy with no hot spots.
Lenses shape, or refract, the light beam shape. This is done to place the light energy precisely over the canopy. Lenses do inhibit the light more than reflectors given the light has to pass through the lens material and loses some of its power.
All of our kits come with holders in order to add and remove Angelina reflectors in order to shape the lights coming out of your LED. Some growers prefer to run without optics, or bare COB. This has benefits in that a reflector will account for an 8% loss in power (PAR) output due to light loss. By running closer to the plant canopy you can better control your light output and also mitigate any losses due to optics (reflectors and/or lenses).
Q: Are all power supplies created the same?
A: No. We use Meanwell brand power supplies designed specifically for use with LEDs. The particular model we use is the HLG series, which is the top of the line power supply offered by Meanwell. It features an IP67 rating and is made of extruded aluminum which acts as its own heatsink helping to dissipate heat. Built in dimming functions as well as constant current are two features that are very important providing the ability to adjust light output while maintaining flicker-free, uninterrupted operation. The power supply has a 7 year warranty from Meanwell.
Q: Why is cooling important with LED Grow Lights - how can I make my lights perform better?
A: The worst thing for LEDs are high operating temperatures. We use a passively cooled design that manages safe operating temperatures without the aid of forced air induction by fans. Maintaining airflow across the pins of the heat sinks aids in dissipating the maximum amount of heat as it speeds up the interchange of hot and cool air. We highly recommend using a clip on oscillating fan or other such fan in order to maintain a slow steady airflow across the heat sinks as this has been shown to lower the heat sink ambient temperature and will also aid in increasing our light's efficiency, and ultimately, PAR output.
Q: What is the importance of a well engineered heatsink?
A: Heat is the main enemy of LEDs. Insufficient cooling can lead to diminished brightness and premature product failure. We use Cooliance and NGL heatsink products - industry leaders in LED cooling. They specialize in thermal management for high wattage COB LEDs. Designed specifically around the Cree CXB3590 and Vero 29 V7 series, these coolers maintain a Tj (thermal junction) temperature well below that recommended by the LED manufacturers. These special engineered pin cushion heat sinks are black anodized single piece extruded aluminum, increasing the heat dissipation effectivity. Pin cushion designs help to provide more surface area for better cooling.
Q: Which model is best for SOG/SCROG? Which model is best for penetration? Which model is best for growing trees?
A: Different combinations of Timber Grow Lights will provide the grower with the maximum configuration to suit any grow. If you have questions about the different models and which is best suited for your needs, contact us, and we would be happy to assist!
Q: What if I don't see the product that I want listed on your website?
A: We do custom builds all the time. Please contact us, and we would be happy to assist!
Q: What is your order lead time?
A: All orders are custom built to each customers individual specifications. Allow up to 6-8 business days for framework orders to be completed and 1-2 business days for kit orders. Please contact us and we would be happy to let you know our current build lead times.
Q: What is your warranty?
A: We offer a (3) three year warranty on all components. Additionally, the Meanwell power supplies we use in all of our products come with a (7) seven year warranty backed by Meanwell.
Q: We build our products with removable potentiometers (dimmers) - why?
A: We make all our potentiometers removable (it's a waterproof fitting between the potentiometer and the power supply). We did that for two reasons:
1. The potentiometer is an analog device and as such is the part of any build most prone to failure. Making it removable helps in the event of a failure- you won't experience any down time and won't have to send the whole power supply (or framework) to us for repair. Just clip a new harness in place.
2. If you run the Meanwell HLG series with the potentiometer disconnected, the wattage at the wall (draw) will actually meet or exceed the stated ratings by Meanwell. This doesn't hurt the fixture and allows you to gain a little more wattage, and in turn, more PAR watts. You can simply connect it whenever you require dimming.
Q: What is the right light for full cycle, vegetative and flowering?
A: All of our lights, unless denoted, are designed for full cycle usage. The operating height and power output will vary according to the stage of growing you are currently in. We recommend 3500K for full cycle usage (generally) and 4000K - 5000K for vegetative growing only.
We also offer a light for flowering only - it comes in a 1750K color temperature, which has a lot of red spectrum for flowering size and growth. The Vero29 1750K line of flowering only lights is located here.
