HYDROPONIC LED 101 – Please Read

• What's the deal with 2w and 3w LED's are they better? In terms of actual PAR (Photosynthetic Active Radiation) output, the 2w and 3w LED's produce more usable light when compared with the 1w LED's. This also means that they will penetrate better. That said, in terms of efficiency the 1w chips are more efficient in Watts / PAR Flux. Overall, the 2w and 3w chips are incredibly bright and allow you to get the additional boost of more power with a lower initial cost.
  
• Why are you the best company to order this from? With over 6000 satisfied customers and 100% feedback, we pride ourselves on customer service and providing the best Hydroponic equipment in the business. Just google us on the forums! We do not cut corners and never make claims that are not legitimate. (No.. a 90w LED will not replace a 400w HPS) just call us and find out. No BS we sell HPS, MH and T5's also we never make claims that are not 100% valid and true.
  
• Why do some of the LED's seem dark or broken? This light has 2 LED's that may seem dim or not to be working at all. This is not the case, they are outside of the visible spectrum and there because of the beneficial properties for plant growth. Don't panic, it is the way it is supposed to be (They are found in the center of the light). 
• Why buy from the USA? Buyer beware, buy from China and wait up to 5 weeks for shipping, and if and when the light is defective, you must pay to ship back to China to claim warranty (if any). Additionally, many of the Ebay sellers in general may advertise one thing and sell you something completely different. Inferior LED chips etc.. etc... buyer beware.
  

• Never buy from any company you can not talk to. 845-504-5723. We are not just an Internet company selling products we do not know anything about. We are a brick and mortar Hydro distributor, call us and find out.
• How is this different than your 6 band HO model and why are you using these bands?  More bands does not mean a better light, these spectrum's are the most efficient and proven wavelenghts for flowering. For over 2 years, Lighthouse has refined the wavelengths of the LED's, this one has a majority of LED's in the 660nm, 630nm range which is perfect for flowering. This light will work for VEG also, but if you are looking for a VEG/Clone light only then we would suggest the HO model. 
• I live in Europe, will this light work here? Worldwide voltage (90v-240v) is standard on all our LED lights.
• How Many Plants will this light cover? We do not exaggerate any claims. Coverage is limited by the physical size of the unit. Our suggested coverage for this light is about 6 sq. ft. Any LED light claiming to cover more area means the seller does not know what they are talking about.
• How does this light compare with HID lighting performance? We sell HID lighting too, so there is no use in us claiming anything that is not 100% ture. LED lights are more money up front, but you save on Electric consumption, cooling costs (which are huge) and bulb replacement. The typical error made is that people do not use enough LEDs. With enough lighting, these 2w LEDs will produce a great yeild. Typically 10% less than a comparable HID system but with faster tomato flowering and lowered operational costs. If you are not with your grow, I personally do not like the idea of an HID light burning unattended.
• Does this light put off much heat? Not at all, you can actually let the plant touch the light, although it's not suggested.
• What makes this LED different than others here? Simply put they use better LEDs and are a reliable company. It's just like using a Chinese HPS bulb vs spending the money on a Hortilux bulb. You get what you pay for, this is the only LED we sell in our storefront because it is the only one that has proven its success.
  

Not all light is created equally. And neither are LED lights! At least not as far as plants are concerned. This is a brand new model which uses the most powerful LED available, 3watt chipset and a redesigned heat sink for reliability. Beware other companies selling inferior Chinese chipsets and not modifying the heatsinks. Multi-watt LED's need special cooling, lighthouse disperses their LED's and has added additional FINS and higher output fans to address this issue. Lighthouse light is unique and the only company to use 425nm blue LED's for better flowering performance. Below is an accurate chart of light spectrum usage by plants.

What does this mean for the indoor grower? This is the wavelength spectrum of white light that plants use. So how does this affect our analysis of HID lights? Below are the light output spectrums of the most popular HPS and MH lights in the market.

The graphs speak for themselves. Neither HPS nor MH provide much lumen output under 580nm. This means that the largest portion of lights used by plants 420nm-455nm is not supplied by either light solution. The peak lumen output is 580nm, 595nm & 615nm. As you can see, that translates into a loss of about 83% efficiency when overlaid with the light used by growing plants. Thus, a 40,000 400W HPS bulb translates into 6800 actual usable lumens. These charts are available from the manufacturers and widely distributed, touting that they are closest to the natural light output of the sun. Thing is, plant's don't use all of the sun.

There are mitigating factors. Our friends at Cornell have informed us that a healthy plant gets the most vegetative boost from blue and ultra-violet wavelengths. We have long known this in the industry because traditional success dictated that vegetative growth is done under MH lights (more blue) and flowering is done under HPS (Red) lights. The later in leaf diameter is outlined in the study attached below:

http://www.sae.org/technical/papers/2001-01-2272

The final analysis is that the most successful growth is found at 420nm, 450nm, 630nm and 660nm wavelengths. Red is slightly more important for flowering but blue produces faster growth and absorption. It is also important for plants to get more 600nm-630nm wavelengths because it is reported that those wavelengths determine leaf diameter. Larger leaves will make a larger plant. And who doesn't love a big tomato plant! Larger leaves lead to larger surface area for further absorption, etc, etc.

Since LED's produce a fairly uniform output +/- 10nm we concluded that given the correct wavelengths, LED's could possible do the job if they lumen output was great enough and they had the correct spectrum.
