We live in the Midwest and its to cold outside to get our garden starts going and ready to plant in the garden when it finally warms up. We don't have a good South facing window to use so these seem like the cheapest and best option. The starts seem to love the lights are are going very well. They are quiet, easy to use, and seems to be well made for as simple as they are. I have bought 2 more sets to use for plants.

One question I have though are the 200 watt total between the 2 units or 200 watt each?

I have it on the top of my aquarium. It lights up the plants that are growing out of the top! It can be adjusted to match what ever you need. At full power it is very bright. I have it on full for the plants but then have to shade it from the rest of the room.

This LED grow light is not only efficient in promoting plant growth, but it also saves energy compared to traditional lights. I've noticed a significant increase in yield with lower electricity costs.

This light is great! I ordered this one as well as the one that is really expensive(forgot the name of it) to see which one was better. They are both built the same and this one from ecogrowhawaii.com emits a little more light. Bang for your buck! Works great.

Easy to install and lasts a long time. Great product!

This is a nice little unit. We have an uninsulated side room to start seed in and were initially using both settings at the same time (which I only realize later was likely actually causing stuff to try to flower as seedlings - I figured the more lumens the better at height but.. lesson learned there).

All the equipment this comes with is pretty handy, the aircraft cable and the power cord is a fair length, and the fans that help keep the unit cool also provide some heat to whatever space its in.

Good price, kept my seedlings growing in minimal natural light so that they could make it to the last frost. Worth the purchase. Happy with the product.

It says the minimum height is a few centimeters but you'll probably want to keep it at least a foot away in general, if not a foot and a half. Leave it on for a while and come back and stick your hand under there - it can put out some heat and damage the plants if you put it too close.
