  1. Easy Conversion to LED 5 Star Review

    Posted by on 10th Feb 2019

    This is the second of 5 planned purchases to change our florescent light fixtures in our Newmar Coach to LED. Easy to do, just snip a few wires and use M4's instruction sheet to make the conversion.

    I have three more florescent to LED conversions to make and I will be done with conversion to LED in the interior. Next up is all exterior marker lighting and turn signals.

    All products that M4LED sells are top notch. Plus they stand behind their products. You can't go wrong purchasing at M4.

  2. Rewired fixture was easy 5 Star Review

    Posted by on 4th Feb 2019

    worked just as advertised. Rewired the flouredcent fixturd per the step by step instructions from the website. very clear instructions with pictures. extra wire and connectors in cluded with the LED bulbs came in handy.

  3. Replaced Thin- Lite 556 fluorescent tubes 5 Star Review

    Posted by on 28th Jan 2019

    Worked great for the lance truck camper thin- lite 556

    less than half the price for a new led fixture .

  4. Quality and Bright! 5 Star Review

    Posted by on 17th Jan 2019

    Almost done upgrading all my lights with M4, got all the little bulbs done. Just installed 2 of these cool white tube lights in a burnt out fluorescent fixture with ballast. Now of course my fixture was very different from the directions but after watching some videos and comparing to the directions it took me about 20 minutes. Will be ordering 3 more sets. Just hope the tube lights last a long time as they are a bit pricey but much cheaper than a whole new fixture. I trust M4 products. Before I found M4 I tried the cheap Chinese ebay led lights (for small fixtures) and they lasted about 2 months (truth!)

  5. Another A+ 5 Star Review

    Posted by on 11th Jan 2019

    This was my second installation of M4 LED tubes in our motorhome. The first was about a year ago when four 48" tubes were installed. They have worked flawlessly since. This install was two 18" tubes in bathroom area. Easy install and they look great. So happy to be rid of those annoying ballasts. Thanks for a great product.

  6. Perfect replacement for 18" fluorescent bulbs 5 Star Review

    Posted by on 6th Jan 2019

    I have been looking for an LED replacement so I could get rid of the fluorescent bulbs which didn't give enough light and the color (Kelvin) was too yellow. The cool white bulbs makes the surfaces of everything it shines on, look new. The lumens from the LED bulbs really lights up the sink and range in our RV. These 18" bulbs were just what I have wanted for a couple of years.

  7. Great product 5 Star Review

    Posted by on 16th Nov 2018

    Installation was easy, just follow the directions.

  8. Exactly as advertised and easy to install 5 Star Review

    Posted by on 10th Oct 2018

    Put in 3 sets of bulbs in 34' motorhome and they work great. Makes everything brighter and cleaner white. Use 1/3 electricity. Would highly recommend.

  9. Great product. 5 Star Review

    Great product and easy to install.

  10. LED Replacement Lights 5 Star Review

    Posted by on 15th Sep 2018

    These LED light tubes are a great replacement for 12 volt fluorescent lights. If the ballast has gone bad in your RV’s fluorescent light fixture. It’s more cost effective to convert the fixture to LED than replace it with another fluorescent fixture. As a bonus you get a better brighter light fixture.
