Product Review

The basic design of the incandescent lamp has not changed much since the late 1800s, when Thomas Alva Edison successfully produced the fist operational electric light bulb. The filament inside an incandescent lamp must be protected so that oxygen does not reach it and cause it to evaporate on contact. Most incandescent lamps are either vacuum-sealed or gas-filled. Incandescent lamp filaments are made of tungsten. Tungsten is a metal that can operate at very high temperatures without evaporating too quickly an resulting in early lamp failure. Incandescent filaments only convert about 10-Percent of the energy used into visible light, so it is necessary to use a material that can withstand extremely high temperatures. Most lamps use a coiled filament design, which has been found to be stronger and deliver better performance.

The 40W bulbs work great and exactly like
the ones I needed to replace in my microwave.

It turns out I could have gotten them a bit
cheaper but that was only a couple of bucks
and the bulbs I did order arrived in only two
days, about 4 days before they were estimated
to arrive.

I am totally happy that I got these. They
work perfectly and the speed of shipping only
adds to my satisfaction with this purchase.

Ordered for GE Spacemaker Microwave Oven to replace a original light bulb. It's working great so far after week of use. The item was shipped in time and packed to prevent damage. I'm happy with the purchase.

These were horrible. I bought 2 so I could have a spare
on hand and within 3 hours they both blew! There goes $$
unnecessarily.

These are definitely not equivalent as amazon said they were.
Thanks amazon for suggesting these as alternates... :(

Never again.
