Almost all the bulbs I buy are Comet 2SMD frosted in some variety of white. I use warm whites behind backglasses/translites and under colored inserts. I use sunlight for GI and under white inserts. About the only time I use color is if it's a visible bulb that needs to be a color other than white or occasionally under a green or red insert. For most inserts warm white looks best .

My only request of Comet would be that it would be nice if you could identify the temperature of white on the bulb without having to plug them in or keep them in their separate baggies. The bulbs all look identical when they aren't plugged in. Aside from that they are awesome bulbs and a great company to order from!
