    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.

  4. 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.

  5. Great products and company 5 Star Review

    Have replaced all the 18-inch florescent tubes and vanity globes in our motorhome with LEDs from M4. The items are good quality, carefully packed and shipped quickly. Instructions for rewiring were included along with wire nuts and extra wire.

    Will be doing more replacements and they will come from M4.

  7. 3 Reasons To Buy M4 LEDs 5 Star Review

    Posted by on 21st Aug 2018

    I recently purchased two of the 18" tube LEDs to replace the florescent bulbs in one of the fixtures in my RV. There are many other brands out there that you can buy that are probably less expensive. The reasons that the M4 bulbs are better are:

    1) The contact pins on the ends of the tubes rotate so that the LEDs can be aimed in the direction that works best.
    2) They have an aluminum heatsink which will prolong the life span of the bulbs.
    3) They are pretty easy to install.

    I will definitely be purchasing more of these LEDs to replace the rest of the florescent tubes in the RV.

    Ordered lights for half the RV a few months ago. Very easy to install/convert with the Youtube video and the provided instructions. Made another order a few weeks ago and now RV is 100% LED. Thanks M4:)

  10. Fixed my problem 5 Star Review

    Posted by on 13th Jul 2018

    These led tubes are great. Easy to retrofit and provide excellent light. These lights corrected my problem with my air conditioner shutting down when i turned on the old fluorescent fixture that i had replaced recently.
