Winterizing, trouble light in water bay

I responded with some of the info below in another thread, but I thought it was pertinent enough to have it's own thread.

Discussion on how to keep water lines from freezing without fully winterizing your coach/TT/5ver, the use of trouble lights came up,

I spoke to a guy with a coach at a campground recently, who said he used the "trouble light" fix to keep his underbelly warm. Even showed me his setup. He was especially proud that he was using an LED trouble light in order to save energy! . . . . . . . . I tried to tactfully explain that he needed to find an old style incandescent 100 watt light bulb if he wanted to generate any heat . . . . . He stated that the LED put out just as much light as the 100 watt incandescent, and used only 17 watts (or thereabouts) of electricity, so that was what he was going to stick with . . . . then we talked about OTHER things . . .

The point is, and most of you probably know this, but for those who are hesitant to ask a "silly" question (which really isn't silly!) LED's are more energy efficient because they emit light more in the spectrum visible to the human eye, not across a broad spectrum of light like an incandescent (old style, filament light bulb). BUT, since they mostly only emit in the visible spectrum, they lack the lower infra red emissions which provide most of the heat!

Moral of the story, if you want to use a light bulb in a trouble light to take the edge off the cold in the water bay or elsewhere, you have to find an old style incandescent light bulb and fixture. Note: since the incandescent bulb by nature generates HEAT, care must be taken to make sure that it is not laying directly against any combustible surface, or positioned in such a way that it can move, ie; if you travel, turn off the light before traveling, and make sure of it's in a safe position once you stop and before you turn the power back on! Enjoy

LOL. He probably got the Led to replace the fluorescent he used before.

With incandescents getting phased out, we may soon need to use expensive infrared "heat lamp" bulbs for this purpose.
