Re: FLORIDA NEAR FREEZING temps on TUES Night.
Wow..Finally something that is my forte..I'm a National Sales Manager for the 4th largest light bulb manufacturer in the world...
Be very careful where the bulb is placed in proximity to fuel sources, oil ectera...Wouldn't want it just laying under the motor (making contact with the flooring) in the bilge area either.
A standard 75-100 watt incandescent bulb can reach upwards of 2,500 degrees C. at the filament.
Don't use anything halogen..Like the Halogen lamps you may have on your motion detectors/security lighting outside your home or workplace. Those devils get 3 to 4x's hotter than the 75 watt Incan lamps!
If I HAD to use a bulb for warmth, I would use an IR (infra red) heat lamp. Commonly used in food service...
Me, I'd wrap the block in an electric blankie set to high and sleep better at night.
