Is there a compact fluorescent bulb that can replace a 500 watt incandescent bulb?
Buying compact fluorescent bulbs can be confusing. Compact fluorescents come in integral and modular designs. The integral type has a ballast and a tubular bulb in a single disposable unit. The modular design features a separate ballast that serves about five bulb replacements before it wears out. The wattages vary between compact fluorescent and incandescent bulbs used for the same applications. I see a few of them online.
