What Do Our Customers Say?
In an effort to reduce the energy cost of my 400W bulb, I purchased this LED light for my hydro-garden.

At first, I was worried that they were not working as well, but it turned out I just needed to lower the lights closer to the plants. With my old 400W bulb I always had the light much higher to not scorch the plants, but these basically need to be right on top of the plants. Since lowering I have noticed the plants are more vibrant and these units seem to be doing an adequate job of replacing my old 400W bulb.

The nicest part is that I don't have to worry about all the heat as these generate very little heat and my energy costs are a fraction of what they used to be.

I will update again when I am ready to harvest and report back if I get as good of a harvest with these as I did with my old bulb. But for now, I am quite pleased.

Malory Perkin

I have been using this product for about a month. I am an avid orchid grower and this is wonderful for my low light orchids. I have noticed a difference in the growing speed and blooming of my orchids already.

I cannot wait to see if there is a huge difference in the electric bills as well!

I have not had any problems with bulbs blowing out. The other great thing is that they barely kick off and heat. So now it is easy to gage temperatures around my temperamental orchids.

Thanks for the great product!

Gissing Keynes

I started with one LED lights, but when I saw how my hibiscus tree flowered and how the agave plants responded, I ordered a second and am now also growing comfrey, 13 pots of gerbera flowers, etc. The agave (boutin blue) are growing the broad leaves, as they do in California. All plants turn towards these lights and I am thrilled with the results.

Also, the lights are cool so my cat can sit in the window and not suffer any uncomfortable temperatures.

A big thanks to grow light LED for allowing us to grow and enjoy healthy plants--without all the hot bulbs and white lights we were never able to quite arrange for optimum growth before.

This is an amazing product.

More Info About 3 watt chip LED grow lights

Sustainable lighting

Efficient lighting is needed for sustainable architecture. A 13 watt LED lamp emits 450 to 650 lumens. which is equivalent to a standard 40 watt incandescent bulb. A standard 40 W incandescent bulb has an expected lifespan of 1,000 hours while an 3W chip LED grow light can continue to operate with reduced efficiency for more than 50,000 hours, 50 times longer than the incandescent bulb.

Energy consumption

One kilowatt-hour of electricity will cause 1.34 pounds (610 g) of CO2 emission. Assuming the average light bulb is on for 10 hours a day, one 40-watt incandescent bulb will cause 196 pounds (89 kg) of CO2 emission per year. The 13-watt LED equivalent will only cause 63 pounds (29 kg) of CO2 over the same time span. A building’s carbon footprint from lighting can be reduced by 68% by exchanging all incandescent bulbs for new LEDs in warm climates. In cold climates, the energy saving may be lower, since more heating is needed to compensate for the lower temperature.

Economically sustainable

LED light bulbs could be a cost-effective option for lighting a home or office space because of their very long lifetimes. Consumer use of LEDs as a replacement for conventional lighting system is currently hampered by the high cost and low efficiency of available products. 2009 DOE testing results showed an average efficacy of 35 lm/W, below that of typical CFLs, and as low as 9 lm/W, worse than standard incandescents. The high initial cost of the commercial LED bulb is due to the expensive sapphire substrate which is key to the production process. The sapphire apparatus must be coupled with a mirror-like collector to reflect light that would otherwise be wasted.
