Hi Flywright,
I had the same problem of forgetting to turn off the engine room lights. It burned out a lot of bulbs and used a lot of power. The engine room originally had four 100 watt incandescents enclosed in hurricane lamp fixtures mounted to the ceiling.
I replaced that with six lamps with 40 watt CFLs in six hurricane lamp fixtures. They produce about the same as a 150 watt incandescent. Don't remember the exact lifetime of the bulbs but I think it was about 10K hours. Not as long as LEDs but longer than I will ever use them.
The engine room is much brighter than it was before and the lights never burn out. I've had them in for about five years and have never had to replace a bulb. I could probably easily use 100 watt CFLs but that seems like overkill. The bubs cost a couple bucks each at your local hardware store.
The hurricane lamp enclosures protect the bulbs from mechanical damage and water accidentally splashed on them. The hurricane lamp fixture can be obtained at Home Depot for about $25 each and install easily.
