Yes, but it is the cheapest.

Cheap doesnt mean good or effective. When you look at an LOA fixture it gives
you two numbers. One is power used one is light produced. The light produced
figure they give you is equal to incandescent this is useless. The power used
figure is the one you need to look at. The lamp in question uses 20 watts and
produces 75 watts=to incandescent. Its a 20 watt lamp. When you start buying
enough of them to get the needed level of light, where does the "cheap" factor
go?
