  1. very bright for only 4 bulbs 5 Star Review

    Posted by on 24th Sep 2018

    Was surprised how well these led bulbs work with only 4 leds per bulb. They work great for reading lights. And priced extremely well.

  2. Hard to find LED Replacement Bulb 5 Star Review

    Posted by on 6th Aug 2018

    I have two recessed spot type reading lights over our bed in our RV. I found these lights to be overly bright and very hot. I began looking in hardware stores, RV stores, on line, etc. to find replacement bulbs and wanted LEDs, for obvious reasons.
    M4 products was the only source for these light that I could find....keep in mind, they are of an unusual size. The replacements are streamline, but fit perfectly and of a perfect brightness for reading and ambiant light without the glare and excessive heat.
    Needless to say, I am very impressed with this supplier and will continue to seek out replacement bulbs from them.....and, refer my RV friends to M4 as well. For all of us who have RVs, we know how these manufactures can go out of their way to find dinasaur lighting fixtures.

  3. I Can Read!!!! 5 Star Review

    Posted by on 20th Jul 2016

    Purchased a pair of these as part of a project to convert our motor coach to LED bulbs. The light from the old bulbs had a definitely yellow tinge to it ... so we went with "cool white" for the replacement bulbs. These 1139IF replacements fit perfectly - and are both brighter and whiter than the bulbs they replaced. My old eyes like 'em a whole bunch!

  4. Really like them 5 Star Review

    Posted by on 9th Oct 2015

    Got these to replace incandescent bulbs in reading lamps over bed in my 04 Pleasure Way . Really like the light. Used them so far on 5 day boondocking outing. Light seems brighter and more focused. My wife noticed the difference and I never told her I made a change. Definitely recommend them.

  5. Our Motorhome never looked so bright... 5 Star Review

    Posted by on 13th Jul 2015

    I changed out all the interior lights in our motorhome and when my wife came for the final inspection, she was awestruck. We love the CW color over the old incandescent yellow bulbs and the heat difference is amazing. Thanks for the quick delivery and expert advice, Steve.

  6. Perfect upgrade for lighting in our RV 5 Star Review

    Posted by on 4th Feb 2015

    We are extremely please with the upgrade to our LED light bulbs. They are energy efficient and so much cooler. The reading lights were so hot we could not touch to adjust their direction.

  7. What a difference, unbeliveable 5 Star Review

    Posted by on 28th Nov 2014

    This made all the difference. We have reading lights and that the old bulbs got so hot we did not want to use them. Then the light was just light, not enough. With the new LED's in place no heat off the light. Then the light is so much better. These are the answer to our problem.

  8. Works Great! 5 Star Review

    Posted by on 14th Sep 2014

    We purchased a couple of these to replace some of the standard reading bulbs in our motor home which we wouldn't use very much because of concern over the heat output of the old bulbs. We are very happy with the quality & output of these bulbs and the fact that they do not get hot! Fast delivery! We will buy from this company again.

  9. Very pleased 5 Star Review

    Posted by on 21st May 2014

    Very happy with quick shipping, price, and bulb quality. Second time ordering from M4 and still a happy customer. Will be back when the last bulbs needed for my retrofit are back in stock.

  10. 1156-4-HP-CW 5 Star Review

    Posted by on 28th Mar 2014

    I installed reading lights in my Weekend Warrior and really like light provided and how they now don't emit any heat at all. Look forward to sitting down relaxing under my new lights.

    I would highly recommend these bulbs.

    Thanks M4LED.
