Great Replacement Bulb
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.

Just what I was looking for
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.

Just what I was looking for
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.

Nice Upgrade!
Recently upgraded to this bulb. I originally purchased the economy bulb but it did not suit our needs. Steve at M4led helped me out with this bulb and so far so good. Steve was a great help and a pleasure to work with. Thank you, Steve!

Top Notch Quality But Pricey
Retrofitted my 2016 Coleman camper with all new LED lights from M4 products. Although the cost was a lot higher then most places I guess/hope you get what you pay for. (TIME WILL TELL) So far (and it's only been 3 weeks and 1 camping trip) we are very pleased with the quality of these bulbs. They give off a bright clean looking light and a very modern feel. Very easy to install. A great upgrade. M4 Note: We are priced below reputable brands and offer better materials and features. There are less expensive LED on the market, but they are inferior and generally not made specifically for RV use.

The light is much brighter than the regular type bulb it replaced. We are very pleased with purchase. We sent a picture of our light fixture and the company told us what type bulb to purchase.
