60 ° concentrating cup kit silver surface temperature oil spray.
The back of the shell is made of 2.5mm thick pad of paper, the outer surface temperature of black spray paint waterproof.
Can replace 3 to 5 times the power of high pressure sodium than traditional high pressure sodium and metal halide lamps can save 80% of energy.
High light efficiency, 90% of light emitted can be absorbed by plants. But the traditional high-pressure sodium lamps and metal halide lamps, only 8-10% of the light effect.
With thick aluminum plate substrate compared to conventional glass filler panels easy maintenance, better thermal conductivity, the product of all the materials used ring to meet environmental requirements, do not contain mercury, lead and heavy metals harmful substances
45 'true' watts, but rule of thumb with leds is that they put out roughly twice what they consume. So it would be safe to say it's comparable to an 80watt HID it's actual draw with a kill-a-watt meter is around 34.3W, which means they're powering the LED's at 76% of their maximum capacity of 45W, which is completely typical for proper lifespan

Top customer reviews
based on some of the negative reviews I was a little skeptical that this was going to be a pretend grow light and not usable.
on first impressions I like this light for the money in both design and function.
I want to try raising some bonsai indoors as we now live in an apartment with only north facing windows, no direct sunlight and not much indirect.
I agree with what others have said about this light, but I will restate them here:
+ bright; don't look at the led array when you first plug it in, I did, not painful but they sure are bright.
+ narrow beam cast; 18" up: gives a 18" 'bright' area on the ground which falls close to zero light 40" along the ground when viewed at night.
+ low profile, so it looks better in my living area.
+ the leds are recessed in the fixture so not only is the light 'focused' but side light and eye strain doesn't happen; ie one doesn't see the actual leds when the light fixture is at eye level.
+ design of the light is nice; yes it's cheap plastic to the touch, but doesn't look cheap.
+ the hanging system is well done, cheap, but works well.
tip: if one assembles the 2 hanger wires such a single strand goes to opposite sides it allows the light fixture to be easily and with stability 'tilted' from horizontal, both front/back and left/right.
+ the power connector has a nice tight fit; I had to give it some effort to insert the plug into the light fixture; I wanted a longer cord so I used a 'computer' power cord I had that was 10' long; ie nice it uses a standard power connector.
don't know if it's going to be bright enough for my bonsai, but will try to remember to update this review after a few weeks.
update 8.7.2015: it's been 3 weeks now and my bonsai are doing just fine.
my hybrid: papillosus x impressus (california lilac) lost a dozen or so leaves, but nothing the last week or so. I suspect the leave loss was due to me downsizing the bonsai and not watering enough, ie daily. Since I figured the watering out, all is well. The green mound juniper seems to like these lights too. Both bonsai show new growth and color(when taken away from these strong blue/red lights <grin>).
I have the lights come on at 6am and off at 10pm.
the lights are aprox 9" from the top of the bonsai, which also places the lights 22" off the 'floor', ie bottom of the pots.
-The market is still widely unknown by people, there are many extremely overpriced options. Companies have taken advantage of this
-More expensive, higher wattage bulbs are not indicative of more PAR (Photo-synthetically active radiation) for your plants, but deeper penetration.
-coverage of areas with LEDs is most important, think of a design you can deliver it best across your area.
-Look into adding white and orange spectrum to the blue and red, not needed but will deliver best results. Red is most important, blue secondary and white and orange should be used in small supplemental amounts. I am currently having great success without white and orange LEDs, but it is widely accepted there is a chlorophyll that relies on the middle spectrum for ideal growth.
With this being said find a place for your grow, cover the whole thing in mylar (look up mylar roll on amazon) and use these, they do work. And look noticeably brighter than in the pictures. The highest light intensity plants are peppers, tomatoes and Marijuana. I have sprouted a wide range of peppers much quicker than average, many people have also had great success with tomatoes. Growing marijuana with 2 of these lights in a smaller area, and 2 pure red LED panel lights (on amazon too) with mylar and a proper setup will reward many many ounces, depending on amount of plants, as you can expect with other more expensive LED lights but at only 100W total. The difference is most other expensive lights are setup to give people a feel similar to HPS, when they're no where near the same. This light can be very close to the plant, inches away if needed for the heaviest fruiting or budding (until stress is noticed). or a couple feet away for general vegetative growing, to increase the spread (and the mylar will reflect most all) where many other grow lights are made to be far away from the plants, with higher wattage LEDs. I've seen many Aerogarden LEDs (I wanna say 14W?) with mostly white, and spots of red and blue spectrum achieve the same things as some 90W LED lights.
When it comes down to it, treat these like light blankets for your plants instead of "sun lamps" you're hanging far above. There are definitely 2 approaches to it all.
