Finally got some CF's in format other than typical spiral at the local Home Despot... which was timely as one of the spirals in the bathroom had quit working, and they'd pissed me off anyway since the bathroom light fixture was designed for the big round globe light bulbs.
First ones I saw were some "Bright Effects" 40W equivalents, located prominently in a sale rack. so I bought some, got them home, and was very, very disappointed. Warm up time could be measured with a sundial, initial brightness was approximately "night light" and there was noticeable variation between the color of the three bulbs I'd installed. Highly not recommended.
Had to go back to the store to get some other stuff and saw that they also now carry "n:vision" brand CF's also in round bulb format. picked up some 14W "60W equivalent" n:visions, much better. these are almost full brightness at turn on and the color is nice and even.
both are made in China and I have not seen any other options available in this format.
just thought I'd share...
