I tried to look for that light at HD and couldnt find it. I went with a coil light and a cheap-o reflector from HD. The light is 5100K 65 or 75W I cant remember and it only uses like 16W. My cheato and sea grapes seem to love the light! I know Marc was talking about heat with that reflector, but honestly I havnt noticed much of a heat release from it. Tho if you do find that encased bulb, I think it would be wise to go that route and no reflector. Just make sure you get the bulb that has the full reflective inside, there are two types, one has a full reflective inside and one has a dull looking coat, I'll assume (and this is only because I know the properties of lighting from my job) but the dull coat wont give you the same effect as the shiny one that that pic above has. There was one with that shiny coat at the HD I went to but the K rating was around 2700. You could go with that bulb but as Marc states youre going to get about 1/2 maybe less of growth on your macros.
