  1. Excellent Product well made and lasts. 5 Star Review

    Posted by on 7th Nov 2017

    Product meets specifications and throws out alot light. Well made and not the cheap china made like other LEDs I have bought via Amazon. Delivery was prompt.

  2. 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.

  3. 100% Working upon installation and bright 5 Star Review

    Posted by on 9th Aug 2017

    M4 Products is the best company to do business with. Not only do they have a first rate product, their customer service is beyond any company in America that I have dealt with. My product was missing from the mailbox (USPS said they delivered it there). After a lot of checking with USPS and getting no where, M4 sent a 2nd batch to me for no cost on my part. Can you believe that? Owner is awesome.

  4. 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.

  5. 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.

  6. 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!

  7. RV LEDS 5 Star Review

    Posted by on 19th Apr 2017

    Bought them for the motorhome and they work great.

  8. 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....

  9. 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.

  10. 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.
