    Posted by on 19th Aug 2016

    I ordered several Bulbs and arrived on the East Coast min three days. Can't beat that. I have installed the bulbs and all worked and the color is just what we wanted. Thanks M4. Will be ordering more soon.

  2. very bright lites 5 Star Review

  3. Very good 4 Star Review

    Posted by on 25th Aug 2015

    I like the LED lighting very much. They are very bright. One thing I don't like is that they cast a very faint blue band of light on the ceiling of the camper. I also noticed that on at least one of the lights one of the LEDs is not on. It looked like one of the lights was not the same color as the others so I took the lenses off for a better look. I think the color was in the lens or the angle I was looking from but I noticed one of the LEDs was off.
    We just returned from 8 weeks on the road but we tried very hard to have electric so we could have air conditioning. Therefore I have not been able to determine how long my battery will last with the LEDs.

    M4 Notes: This is Cool White which is closest to the blue spectrum. Though they do not show as blue, if the light refracting off of anything it could bend it blue which is a guess as to why you see a stripe. This has never been reported before. This item is also available in Warm and Natural White which is away from the blue scale.

    Please contact us with any / LED chip out issues to be resolved. Unfortunately altering the LED by removing the designed in protective cover / diffuser does void the warranty though. But if there are every any concerns with any product, please contact us first.

  4. GREAT!!!! 5 Star Review

    Posted by on 5th Jun 2015

    The M4 site is an outstanding resource, the bulbs are exactly as described, and the pricing can't be beat. I recently retrofitted our RV with LEDs. We used this bulb as well as 7 other bulb types, 53 bulbs total. Every bulb we purchased for every application was EXACTLY as described and matched our needs perfectly. No need to look elsewhere, M4LED is THE PLACE for RV LEDs!!!!

  6. OK 4 Star Review

    Posted by on 22nd May 2015

    I only wish that I could also have gotten the warm white lights at the same time.
    I will order them when they become available, plus a couple of others I was looking at for my trailer.

  7. perfect retrofit 5 Star Review

    Posted by on 27th Jan 2015

    What more can I say , this LED spotlight (reading light) fit perfectly and was an easy fit.

  8. Nicde replacement for readings over the bed 5 Star Review

    Posted by on 20th Aug 2014

    Traded out one light and compared. The light that came with the trailer is a lot warmer. The amp reading on the bulb that it replaced was 2.8 amps. With is conversion I am only using 7.5% of the power required of the original bulb. So now I will be able to read the whole book before the battery dies rather than just one chapter.

  9. Bright Light 5 Star Review

    Posted by on 17th Jun 2014

    It is a very bright light. Good for area lighting. If you are going to read I would suggest the warmer color.
