Question: Are these bulbs dimable? I'm hoping to use it in a maplight fixture that has a diming rheostat.
Document: Very bright bulb. I use it in my jeep and it lights up the engine bay nicely. Just the right size for the stock light fixture. Any larger bulb wouldn't fit right.
I use one of the cool white 36 LED white LEDs along with one of the warm white 36 LED in a two lamp fixture in the bathroom of my RV. The combination gives a pleasant "natural" light my wife prefers, compared to using only one type or the other, and while they use less than 20% of the power the orginal incandescents used, they seem just as bright. A good choice for RVs running on batteries in the boonies.
These bulbs are an alternative to replacing an entire fixture in an RV or trailer. While a little pricy, they are the best value I've found for what they do. I purchased these and some brighter (from the same company) to have both high and low light levels in our trailer. If you want to stretch the run-time of your battery while dry-camping, this is an excellent way to go.
Nice even light in all directions. Low drain and long lasting. I'm using it on an RV for the entry light.
bought for my porch light on motorhome ,lots of room even a long a they are .. i'm thinking of putting some tin foil behind them to make them even brighter . very good light sorse  i highly recommend these.
By itself I'm not excited about the color . The brightness is decent . But when used as a companion light to a warm white I like the result . Low power consumption is a great plus . Seems so far to be well made .
In addition, I find the light to be both Brighter and better for reading than the automotive tail lamps which are standard issue. Fits in the existing fixture-whats not to like.
And easy decision to make.I found one bulb was not working. I am retired my old bulb and it didn't work. I suspect the fixture has some corrosion as these are very reliable.
Everything considered, I would definitely recommend these lights, I'm pretty pleased by them. The reason I didn't give them a five-star rating is because I really wouldn't mind if they were a bit brighter, but seriously--it's a small enough difference I doubt anyone would notice.
I didn't realize an LED light existed in this format until I searched for a replacement bulb for my vintage desk lamp. It works great and puts out a good amount of light for such a small bulb. It obviously costs a lot more than the normal ones, but I'm sure it will last a long longer as well.
Answer: yes
