  1. Buy here 5 Star Review

    Posted by on 24th Aug 2017

    The best place I have found to purchase quality LED replacement bulbs. Customer service is excellent. Fast shipping.

  2. Very satisfied 5 Star Review

    Posted by on 16th Jun 2017

    I just received the 2 LED 921-24-5050-CW and installed them in the bathroom of the RV. My wife is very happy because they give so much light for her while she does her morning makeup. So, if my wife is happy, I am happy. I have just completed an order for additional bulbs.

  3. LED 921-24-5050 replacement for #921 incandesent bulbs 5 Star Review

    Posted by on 15th May 2017

    I'm planning on taking my 1998 pop-up camper to Yellowstone in August and it's not likely I'll be at a campsite with electric. It will be imperative to conserve battery power. The 4 LED light replacements will do the trick, taking about 1/7th the power (0.17 amp vs 1.2 amp for each of the #921 originals) and a brighter light. As mentioned by others, is a tighter fit than the #921 bulbs they replace but there doesn't appear to any problem with clearance once in. I handled them with a Kleenex so as not to get oils on my fingers on any parts of the bulb. The order was filled quickly and shipping was really fast. I did have a problem with one of the bulbs ordered but a replacement was sent out at no charge. The wider voltage range (10-30v) for these bulbs is must for older units where voltage can vary. Fantastic customer service.

  4. Love the daylight 5 Star Review

    Posted by on 2nd May 2017

    I ordered six of the 921-24-5050 -CW to replaced over dinning table and ceiling in my Trailer. They were so easy to replace the standard bulbs. I likes them so well I ordered 5 more so all of the inside of my trailer lighting was updated. Love them.
    A lot less drain on battery too!

  5. RV LEDS 5 Star Review

  6. M4LED That Shines... 5 Star Review

    Posted by on 31st Mar 2017

    I order 6 each of these # 921-24-5050-CW LED Lamps to update my lighting in my new 5th Wheel. They greatly increased my light output, with the best feature of lowering my current draw off my battery system to just a sipping of energy.
    These new LED Lamps are a win/win for any RV'r who takes a rig on the road....

  7. I can see my food 5 Star Review

    Posted by on 10th Dec 2016

    We installed these in our chandelier over our table on a dimmer and now we can see our food before we taste it. We had purchased some inexpensive leds and they would hardly change brightness. We got a 10 pack and plan to use them in the bedroom too where my wife loved to read mysteries.

  8. Heat generated 5 Star Review

    Posted by on 6th Sep 2016

    Very pleased with the difference in heat generated compared to the 921 lights I replaced. I will definitely be ordering more M4 products.

  9. Very tight fit 4 Star Review

    Posted by on 26th Jul 2016

    Very happy with the light output from these lamps. Not having to worry about polarity like on other wedge lamps purchased was a nice plus. Was concerned about installing the lamps as the wedge base was very tight, and need more force than I would have expected was afraid of damaging the assembly. Now able to light my RV using far less power. Ordered on Tuesday night and installed them 4 night later.

    M4 Note: Some sockets are tighter than others. When tight align the wedge, then place your finger at the top of the LED. Rock it back and forth slightly while applying pressure to the top and it will drop into place.

  10. Nice and Bright 5 Star Review

    Posted by on 20th Jul 2016

    Purchased these bulbs as part of a project to convert all the lighting in our motor coach to LED bulbs. These 921 replacement bulbs fit the fixtures in the closet and basement of the coach. These bulbs are noticeable brighter and whiter than the bulbs they replaced - which is great considering how they're being used. These bulbs are a "direct swap" replacement for old 921 bulbs - however, I will say that these were definitely very snug fit in the fixture compared to the glass base wedge bulbs they replaced. I had to "lean into 'em" to get them into the base hard enough that I was a little worried that I might damage the fixture itself. Fortunately, they finally popped in - so it was a case of all's well that ends well. I'm loving the bright white light!
