Question: how many bulbs come in a package?
Document: They are a little expensive but I'm certain that cost will come down as we switch to low energy bulbs. When we are camping we need to conserve where ever we can. I would rather pay a couple of bucks now knowing that our battery will last through the night until the solar panel can charge us up again.
I liked installing them over the ones I picked up from Lamps Plus for $10.00 each,  The Lamps Plus Bayonet LED replacement had many more and larger LED's so they were much brighter. I liked the price on these but they are no brighter than the original 12 volt bulbs.
These bulbs works as a great low wattage replacement for the stock incandescent bulbs that come in your RV. I installed one of these in a 2 bulb fixture to compare this with the old bulb side by side. Brightness wise they are VERY close - I would say this is 95% as bright as the original. Color temperature wise - these are about identical so the original bulb.
That night, the incandescent bulbs did not work. Next day I did some digging in the garden and found one of the wire connectors had come undone. Fixed the broken connection, put the LED bulbs back in, and that night - lights!Aside from the aforementioned "operator error", I am pleased with these new bulbs. The color is very close to the incandescent and definitely not as bright. I actually like the amount of light given off a little better for this application.
These are great little lights. I was worried that they wouldn't be bright enough, but they provide plenty of light. The color temperature is different than incandescent, obviously, but the output is very similar. I will buy many more of these next spring.
Great replacement for regular bulbs.....
good price for LED 12 volt and they are just as bright as our 12 volt old bulbs in our RV
We purchased these to replace incandescent bulbs in our motorhome. They fit, but they are not bright enough for any use, let alone reading.
We had been looking for reasonably-priced replacement bulbs mainly for the lower operating temperature as we don't run off battery but seldom. We ordered more for our other lights.
I put this in my exterior porch light on my 30' KZ travel trailer because the standard bulbs kept burning out after a few days.
Answer: yes
