First, some background- a kilowatt is 1000 watts, so 250 watts is 1/4 kilowatt. and a kilowatt-hour is when you use one kilowatt of electricity for an hour. . This is a 250 watt bulb, so if you use it for an hour, that's 250 watt hours, or 1/4 kilowatt-hour. A typical price for electricity is 16¢ per kilowatt-hour, so this bulb would cost you 4¢ per hour, half that in Oklahoma, twice as much in Hawai'i
provides plenty of heat, might want to use with an adjustable output switch to obtain the temperature you need
Nope can’t help with this one, it’s just a heat lamp not a space shuttle!
I would say no, this lamp gets warm but it could not keep the underside of an RV from freezing unless you bought 3-4 of them and sealed the underside in an insulated housing.
I know little about chickens, but if the chickens were not in contact with the light and the light were placed at an appropriate distance from them it seems to me that it would offer a steady and gentle heat source. One could use a thermometer to measure the temperature at various distances from the heat source.
It is always best to used the specific recess light fixtures that is made for it. That way you don't have any problems of overheating, circuit breaker tripping and fire. Depending on the house wiring guages size for the bathroom, breaker box and the specific breaker for that exact fixture in one of these new high end houses you might be ables to get away with it of less than 1/2 hour of used while using the bathroom or taking a bath. If the quality of the wiring, breaker box, and specific breakers failed to do the job due to quality, poor workmanship or defects than you might have a fire that may cuased damages to you, your family and housed. Why take the risked of fire and bodily injuries.
Please consult with your physician regarding potential light therapy.
Yes the lamp produces infrared energy and the red quartz class reduces the visible light and produces a warm look.
Never exceed the wattage rating on the fixture. There should be a sticker near the socket that indicates the maximum wattage and the type of bulb that fixture can use safely.
