Great RV retrofit
I used this bulb to retrofit my 2007 Airstream range hood incondescent bulb. Great improvement, equal light lumens with 90% less power. This is not only more efficent and cost savings in means many more days of dry camping!

Great Lights at a affordable pric
I replaced 10 bulbs and used them over the July 4th week and they helped me save battery power of my travel trailer all week with only one small recharge over the week. Primitive camping. I will be replacing more. Thank you. Rick F

Best, Brightest LED for RVs yet
This is our chosen RV replacemnet light, at least as bright as and possibly brighter than 921s! And better color especially if dimmed. Only issue is that contact leads sometimes need to be bent around a bit for a reliable contact.

Great Price and Product
Replaced 921 bulbs with Warm White 5050 LED Light Bulb was a little concerned that they would not be as bright as OEM bulbs. After replacing a few bulbs and being surprised how nice that they light up the trailer, I've gone ahead and ordered replacement for all fixtures. True test will be on our first outing and seeing how long the batteries last before having to kick on the generator for a recharge. Jayco JayFeather 254 Trailer

Finally, a great product at a great price!
I have been playing this LED game a long time.. I have bought cheap lights on E-crapbay and some expensive ones made in the US and these are the best lights I have ever used! Great light output, great quality, and best of all great service.. Where were you guys a few years ago, it would have saved me lots of money... Thanks M4 for fulfilling my LED dreams!!!

Replaced 921 light bulbs
I bought two of these to try and was very pleased with the results. I had tried others and was not happy. I have now bought enough to replace the rest of the 921 bulbs in my 5th wheel

Replaced OEM lights in new motorhome
The new Class C motorhome that I bought three months ago came loaded with "921" incandescent lights. I was concerned that switching to LED's would take an engineering degree! But the website was well-designed and made it easy to figure out which LED light I wanted. Shipping was quick. The lights arrived within a couple of days of ordering. replacing the OEM lights was easy. All I had to do was remove the lighting lens, pull out the old bulb and push in the new LED. Slick and easy! I just ordered some more. This time I'm getting the flat, not tubular, lights. I'm hoping they'll direct just a little more light into the areas I use for reading.
