  1. Very Happy 5 Star Review

    Posted by on 20th Jun 2017

    Same warm white as incandescent, maybe a little brighter. Left them on for over an hour - stayed cool. The 921's I replaced had melted two of the fixtures. HIGHLY RECOMMEND THESE M4 LED'S.

  2. Excellent Choice 5 Star Review

    Posted by on 1st Jun 2017

    We found out about m4Products on YouTube. We ordered a couple LED's for our RV and were very pleased. Then we ordered enough to almost finish off replacing all the original bulbs with LED's. We will be ordering a few more shortly. Good product! Good customer service too!

  3. Still Happy 5 Star Review

    Posted by on 26th May 2017

    After a small problem, it was quickly, and completely resolved. So happy with M4!
    6 years of dealing with them.

  4. so far so good 5 Star Review

    Posted by on 10th May 2017

    I've purchased over 40 bulbs in the past few years. The only small issue I have is the interference with the radio reception when using the bulbs on certain circuits. May be unavoidable with LEDs at this point in time. There was one bulb that broke while installing. The wire contact on the wedge base fell off. I'm going to return it and hope they make it right. I've been happy with M4, and believe they will fix this promptly.

  5. Great replacements for incandescent bulbs 5 Star Review

  7. light for rv kitchen 4 Star Review

    Posted by on 8th Dec 2016

    Great shipping, arrived quickly. This warm white wedge base led in a little more yellow than I expected. It does give much more light than the incandescent bulb that I replaced.

  8. Delivers as advertised 5 Star Review

    Posted by on 15th Nov 2016

    I bought a few bulbs to replace the stock incandescent bulbs that burned out on our last trip. The bulbs were delivered very quickly and were very well packaged. The bulbs are just a bit brighter than stock and as others have said, the have a great comfortable color. They are not harsh at all. Two days later I ordered replacements for the rest of my lights.

    Yes it can get a little pricey to upgrade from incandescent bulbs but is well worth it in the long run. These replacement bulbs are made of the highest quality and the shipping is fast and efficient..Thank you m4led.com.

  10. Great LED Lights. 5 Star Review

    Posted by on 8th Nov 2016

    These bulbs arrived quickly and work great. The light has a warm color. The bulbs are noticeably cooler than the ones that were replaced.
