  1. easy install 5 Star Review

    Good light color. Not to white or to yellow Easy install. Just make one end positive and one end negative. No additional parts.

  2. good product 3 Star Review

    Posted by on 1st Aug 2018

    The lights were very east to install, I was wanting a brighter light but these are ok. Delevery was very fast and all lights worked when installed.

    M4 Note: John, these are 10% brighter than fluorescent -if- you ordered the same color range (kelvin). This order is 3200k Warm White, ordering 4500k Natural White or 6000k Cool White would give you a whiter visibly brighter light. Contact me with any options / concerns / questions, glad to help. - Steve

    I upgraded four 2-bulb florescent fixtures in 1 evening. The LEDs output is crisp & attractive. Highly recommended.

  4. Easy to install 5 Star Review

    Posted by on 8th Feb 2018

    I have five fixtures of this size in my RV. I only ordered 2 tubes originally to replace one fixture just to make sure I was capable of changing the wiring. With the attached instructions, including a photo of how the wiring should look, it was a very simple task. I have ordered and received the remaining 8 tubes to replace the final four fixtures. I received them in two days from the time I placed my order, not bad considering cross country. I have four of the 12 inch fixtures also that are going to be replaced with the same type tubes.

  5. Simple install 5 Star Review

    Posted by on 6th Feb 2018

    I only ordered 2 LED tubes to replace 2 florescent tubes in 1 fixture. I first wanted to make sure I was capable of re-working the existing wiring, to bypass the ballast. The task was simple. Great instructions are provided. Bulbs will be ordered for the remaining 4 fixtures.

  6. great project 5 Star Review

    Posted by on 18th Jan 2018

    i have a 1950 vintage travel trailer which has various linear t-8 fluorescents i converted to 12 volt dc some 30 years ago.

    having these LED replacements has upped the game again with no mercury, instant on and higher efficiency.

    i love the 3200K color temperature as it matches the cozy warm incandescent color temperature. i just wish the 20 watt option was also available in the warmer color.

    the replacements are very high quality, and the rotating ends allow for accurate aiming. i could not be happier with this retrofit.

  7. Im L ovin' It {them}! 5 Star Review

    Posted by on 22nd Sep 2017

    Bought a new to me {used) Fleetwood Bounder and just finished switching out all of the interior bulbs and headlights to LED. Steve answered various installation questions from me promptly and live over the phone too. Two things really stand out from the process.
    1. The speed at which the orders come is truly remarkable. It seems like they are driving them over from across town. Granted I only live a state away but they are seriously fast at processing.
    2. They have warm white tube bulbs. I hated the inherited cool whites, it felt like I was eating dinner in my doctor's office. Tried natural whites in some of the other lights and they were marginally better, good for reading maps etc. but still not the ambience I was looking for. Warm white is so nice. Thanks M4!!

  8. An essential mod for your RV 5 Star Review

    Posted by on 12th Sep 2017

    These lights are just fantastic, the light is warm and even, the retrofit is not too difficult if you can follow the instructions. We removed the old ballasts to save the weight and room under the ballast cover, that will take a punch and drill if they are riveted in place.

    Great step forward when you swap out your florescent tube for an LEDs set in a round tube. I was impressed with clarity of instructions for re-wiring a florescent fixture, and by the packaging of these tubes by M4. Great job and prompt shipment!

    Got to tell you if you want the best and quality then you have to pay up! Quality A++. Perfect lighting. Yes, they are pricey, but I am confident that these will be the last time I have to buy these.
