      Comments about Westinghouse 375 Watt, 120 Volt BR40 Clear Heat Lamp Reflector Bulb:

      These bulbs are used in an electric heater. So far they are working great. When I bought the heater 5 years ago the salesman told me the bulbs would be about $25 each so I was wonderfully surprised to find them for under $10 each. They arrived unbroken and very quickly.

              On these early dark evenings in the cold, it is pleasant to sit and work on the laptop or on paperwork in the bright white light and warmth of this heat lamp. I've put it in floor lamp that shines directly on me and on what my project is. I also have placed another floor lamp with the bright white lamp at the vanity where I do my make-up for the additional lighting needed for that job and for a little more warmth while I'm there.
