The Truth about Wavelengths

LEDs have existed for almost 50 years, but until recently, they lacked the light output and energy efficiency necessary to make them a viable alternative to traditional lighting solutions.  Since 2008 the lumen output per watt of LEDs has doubled, and the best LEDs are now on par with HID lights in terms of lumens/watt with one exception, they are far more efficient. 

Based on research done by scientists at Cornell University and other horticultural centers, Lighthouse Hydro has developed LED lighting products that optimize the usable light wavelengths absorbed by your plants. Neither HPS nor MH bulbs provide significant light output below the 580nm wavelength. This means that one of the largest portions of the light spectrum used by plants (420-455nm) is not supplied by either HID product. Additionally, the majority of HID output is in the green-yellow spectrum which is not only reflected by plants but also barely used in Photosynthetic reactions. The most important wavelengths for plant growth and flowering is found at the 420nm, 450nm, 630nm, and 660nm wavelengths.  Red is more important for flowering and yields, and blue more important for node intervals & faster growth and absorption. We deliver these wavelengths, scientifically balanced for maximum efficiency. What once was 70% of light wasted is now light harvested. Lighthouse Hydro LEDs use a optimized blend of individual 60 degree, 90 degree, and 120 degree LED chips.  In the configuration Lighthouse Hydro has designed, light coverage for the grow area is maximized and light penetration is increased when compared to lights using a single spread angle LED light. 

Not all light is created equally. And neither are LED lights! At least not as far as plants are concerned. HPS, MH and T5 bulbs produce a spectrum that is fixed and based on the filament or phosphors in the bulb. Even the industry's best bulbs are only 32% efficient.  

The above graph is the output of one of the leading HPS bulbs in the market. As you can see the majority of light emitted is in the yellow and green spectrum. These colors are NOT used by plants (hence the reason the leaves are colored green, they reflect it!) 

Take a look at the graph below, this is the spectrum that the plants actually USE!
This is commonly referred to as the "Photosynthetic Action Spectrum".  

Here is a graph of the light output of the Lighthouse Hydro UV models:

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 70% efficiency when overlaid with the light used by growing plants. Thus, a 40,000 400W HPS bulb translates into 12000 actual usable lumens. These charts are available from the HID bulb manufacturers and widely distributed, touting that they are closest to the natural light output of the sun. The most important thing is, plant's don't use all the light from the sun, they flourish when very specifically tailored wavelengths are used.

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 630nm-660nm 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.

I live in Europe, will this light work here?

Worldwide voltage (85v-265v) is standard on all our LED lights. Customers in the UK will receive a UK power cord. Customers in Europe will receive an EU power cord. Customers in Australia will receive an AU power cord. If you are still concerned about power compatibility in your specific country, please call or email us.  

How does this light compare with HID lighting performance?

LED lights are more money up front, but you save about 50% on the electrical consumption of the light, cooling costs (very expensive in the summer) and annual bulb replacement. You can look forward to paying back the cost of the light in electricity savings over about 12 months of use. The most common error made when using LEDs is that people do not use enough of them. Follow the guidelines for recommended coverage area, and your LEDs will impress you with their yield. The much reduced heat output of LEDs when compared with HPS/MH bulbs also substantially reduces the risk of a fire hazard, especially in an enclosed space.

Does this light put off much heat?

LEDs are the most efficient lights in existence today. They produce so little heat; you can actually let the plant touch the light (although it's not recommended - as you will reduce the size of your growing area). Any heat produced by the unit is absorbed by the heat sink and dissipation by the fans in the rear of the light.
