  1. 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.

  2. 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.

  3. 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!

  4. Cold White light bulb 5 Star Review

    Posted by on 9th Jul 2016

    Product shipped very quickly despite postal service miss handling here in Texas. Product once again far surpassed my expatation. Brighter and better light than original LED.

  5. The cool white is Very WHITE 5 Star Review

    Posted by on 27th Jun 2016

    The light is good to read by, more of a direct light than general lighting. Takes some getting used to because it is a VERY VERY WHITE light. Not that it's a bad thing, just seems unnatural for what we are used to, No flickering and no yellow, imagine that!?

    Super fast delivery and great packaging! Will definitely order more from, and will recommend M4 in the future!

  6. 921 replacement buld 5 Star Review

    Posted by on 22nd Jun 2016

    This bulb far exceeded my expatations. Was much brighter that expected. Perfect for the application that I was using it for which was a dark closet.

  7. great bulb 5 Star Review

    these are wonderful products, my whole RV is now LED from m4 products. Very nice products and wonderful service!

  8. Great Replacement Bulb 5 Star Review

    Posted by on 2nd Jun 2016

    We got tired of the energy draw and the heat put off by the 921's in our camper. Did some research around and M4 was the way to go. Had a single question about an application of a bulb and was contacted immediately by Steve. The 921-24-5050-CW Cool White bulbs put off a nice, bright, white light that fits our needs while producing zero heat.

    Great customer service, fast shipping, and a superior product. We will order again when we finish our LED retrofit.

  9. Just what I was looking for 5 Star Review

    Posted by on 5th Apr 2016

    921- 24 50/50 cool white LED Bulbs. These lights exceeding my expectations. If you are looking for lights like I have been for a number of years, and have tried many different kinds. These lights are for you. They are the brightest lights I have ever tried. They will light up the inside of your RV. The lights are so bright that in my bedroom area I only have one light per fixture, And that light put out more light than two 921 incandescent bulbs. These lights do have a bluish tent, if you don't like that than you will need to order the warm lights. I wish they had the natural in these lights. They don't have the natural in these you would have to order the elite series. They do have the natural lighting in them. These are awesome bulbs, and I will be buying more. And very fast shipping. I am very impressed with the M4 Products shipping. I live in California, Which I am about 8 hours away from them. I ordered the lights one day and received them the next.

    Very fast service, lamps are just what I wanted. time will tell how they last, but some of the incandescent lamps I replaced were already turning dark. My RV is only a year old.
