Brightest & smallest of the screw-in fluorescents; plus instant-on
on February 23, 2008
SYLVANIA 23W Compact Fluorescent Micro Mini
These bulbs are comparable to 100 watt incandescents in light output, so they are quite bright. I can't vouch for longevity, since we only recently began using them. However, they come on instantly at nearly full brightness and they don't flicker, which was reason enough for me to stop using other brands. (Full brightness takes a few seconds.)
They are about 25% smaller than comparable mini fluorescent screw-ins, so they will fit in fixtures where the competition won't. For example, I just bought an overhead 4-light fixture, and installed two of these (since that's all I had) and two of the old style 23 watt compact fluorescent bulbs. Besides sticking out past the glass bowls, the old bulbs gave off a slight yellowish glow. The Micro Mini's light is bright white, similar to daylight.
Another plus: with these bulbs, you can get more light from your small lamps. That is, some small lamps or fixtures are rated for no more than a 25, 40, or 60 watt incandescent bulb. This has nothing to do with the lamp's wiring capacity. Instead, it's because incandescent bulbs of greater wattage could get hot enough to be a fire hazard. The solution is, don't use incandescent bulbs. These 23-watt Micro Minis produce the light of a 100-watt incandescent but get no hotter than a 25 watt incandescent bulb. While that's true for any comparably rated fluorescent bulb, this one is small enough to fit in many small fixtures. For example, we have a recessed stair fixture rated for a maximum incandescent bulb of 25 watts, which doesn't give off much light. With this (or the smaller size) Micro Mini bulb, there's plenty of light.
This product is a technological leap in Energy Star screw-in fluorescent bulbs.
