Q: I just placed my order, how long does it take for my light(s) to ship?
A: Lights usually ship within 5 business days of placing an order. Once they are shipped, it generally takes an additional 2-3 business days to arrive. Most customers receive their lights within 10 days, however shipping times can take 2-3 weeks depending on stock and your location.
Q: I received my tracking number, but it is not working, what should I do?
A: The number we supply is a reference number, which is standard for international packages. For up-to-date information on your package location, you'll need to go here: UPS Reference # Tracking. Please understand that it can take up to 24 hours from the time your package is shipped, prior to any records being available online.
Q: I noticed that some companies use orange in their grow lights, but you do not. Is there a reason for this?
A: Orange has very little to no benefit for plant growth. In our experiments using 612nm orange LED's, they actually had negative effects on young seedlings and clones, especially when placed within 10" of the canopy. Some companies use orange, because they base their designs on aging patented research, filed by Solar Oasis. This company made reference to orange having a positive effect on carotenoid function, yet a simple search on Google will inform you that carotenoids absorb primarily blue light, not orange. Based on our testing (and all of the scientific data we have compiled on photosynthesis), the use of orange in any grow light is simply wasted energy.
Q: Why do you use infrared in your LED grow lights?
A: Infrared supplies the necessary heat required for plant respiration and development. Infrared also increases the rate at which a plant's cell is able to regenerate and repair itself. This equates to healthier and faster growing plants.
Q: Why don't you use Ultra Violet (UV) in your LED grow lights?
A: UV is not currently a cost-effective option for our lights. Some companies sell you lights with 390nm or 420nm UV LED's, although UV in this range does not produce beneficial results with your plants. If the ratio of UV is too high, it can actualy damage your plants and decrease your yields, so we don't recommend using any UV unless it is in the proper range. The correct nm UV is in the 285-315nm range, and current 1W LED's cost in excess of $90 each. For this reason, we recommend that if you wish to supplement your garden with UV, that you purchase cheap CFL style, UV bulbs available online.
Q: I just received my new grow light, but it appears that some of the LED's are not working. Is there a problem with my light?
A: There are a small number of infrared LED's in each of our light engines, and the light they emit is invisible to our eyes. For this reason, they appear as though they are not working, but rest assured they are.
Q: Why are there so many fans on your LED Grow Lights?
A: LED's are a chip-based light source, which require operation within a certain temperature range, to ensure efficiency and optimal light output. Failure to properly cool the LED's, can result in drastically reduced lifespan and output. We supply ample fans for our grow lights to guarantee they last for years to come, and always operate to their fullest potential.
Q: What is the actual power draw for the 126W unit, with fans and LED's operating?
A: We recently bought a power metering device to give you an exact answer. Our 126W contains 126 x 1W LED's and 6 fans, while having a total power draw of 126W. The reason for this is that LED power supplies are only 90-95% efficient, causing a slight dip in the overall amount of power supplied to the LED's. This eqautes to low power bills and high functionality in a compact design.
Q: Your 318W says it is equal to a 1000W HID, but it only has a 2' x 4' footprint. I use my 1000W HID within a 4' x 4' footprint, so wouldn't it take two units to cover the same area? If so, how are they equivalent?
A: Yes, it would take two 318W units to cover a 4' x 4' area. While LED's are certainly a lot more efficient watt for watt at growing plants, it still requires a similar amount of wattage in order to cover an equal sized area as a HID. The 318W is equal to the 1000W HID in terms of its yielding capabilities, but certainly not it's footprint. This means that you can achieve equivalent yields to a 1000W HID, in half the space using our LED's.
