Par38 led grow light for regufium.

The goal of this light is to make plants or in this case algae to grow fast thanks to the high par it produces. I saw people using them lots of times so I guess it is fine. I saw them sold on ebay for less than 5$..check the prices again:)
 
Dont waste your time. You won't find a par 38 bulb for $5. Cheapest I can source will run right at $30. Go with something like a 5 to 2 red, blue.
