Hey

I bought a 20 watt light (the economic ones) that is made for plants. So i gave it a try and it worked extremely well and its still going well. It produces 900 lumens when you put at at 1 feet from the plant witch is enougth. anyway this is a pic from it. It haves alredy a reflector and produces no heat, so it is perfect for a closet.

See ya

P.S: the lamp is from Sylviana and it costs about 3 to 5 bucks
