Q: How do I select the right wattage for my coverage area?
A: The amount of wattage you select for your coverage area for flowering/full cycle usage is going to be based on it's ability to generate PPFD values of 900-1000 µmol/m²s. Here is a list of typical coverage areas and recommended LED wattages:
2'x2' 200 Watts
3'x3' 400 Watts
4'x4' 600 Watts
5'x5' 900 Watts
Our lights also come with dimmers. If you dim your fixture, you will increase efficiency. This will lead to more energy for the plants and less heat output.
For vegetative growth only, PPFD needs are about half that of flowering (roughly 500 µmol/m²s) which means you will need half as much wattage as you would for full cycle/flowering use.
Q: Do I need a separate light for veg and a separate light for flowering/bloom?
A: No, our lights are for full cycle usage, meaning you need only one light for seed/clone/seedling to harvest. We use LEDs which output a very bright, natural white light and offer color temperatures designed to mimic those of natural sunlight. All lights come with a dimmer so that you can adjust both the power output as well as height above canopy for the different growth cycles.
Q: What is your warranty?
A: We offer a (5) five year warranty on all components.
Q: How high above the plants should I hang my Timber light?
A: Our lights all 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 and can be used very close to the canopy. Most growers operate the lights at 24-36" above the plants and 25-50% output during vegetative growth, gradually lowering the light to 18-24" and 100% output during flowering.
Q: Where are your fixtures made?
A: Our grow lights are engineered and built in California by lighting professionals. Timber Grow Lights are built using top of the line components sourced domestically whenever possible.
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 radiant 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 products, 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 Grow Lights. Plug them in and start to grow.
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 is cooling important with LED Grow Lights - how can I make my lights perform better?
A: 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. Designed specifically for COB LEDs, these heat sinks maintain a Tj (thermal junction) temperature well below that recommended by the LED manufacturers. These special engineered pin cushion heat sinks are anodized single piece extruded aluminum, increasing the heat dissipation effectivity. Pin cushion designs help to provide more surface area for better cooling.
Q: Do you ship discreet?
A: Yes - all lights are shipped in plain brown boxes with no reference to 'grow lights'. Our return address simply says 'Timber' on the label. Additionally, we offer $25 flat rate shipping on all of our lights.
