Grest lighting for RV!
We researched and read the reviews before purchasing the 921-24-5050-CW Cool White 5050 SMD Light Bulb with Wedge Base. We purchased a couple bulbs locally at Napa and Walmart to compare because we didn't know what we needed or how they all would compare. We are very impressed!! We are using these in our RV and where there were 2 regular bulbs we are only going to need to use 1 of these!! A great find. Fast shipping, was here almost before I completed the order :)

Great LED Bulb
I bought 3 different bulbs to try before I bought this one. This one had the best white light output by far. Construction was the best of all. Bought 15 more to put in all my RV lights

These lights are awesome!
The LEDs that I purchased from you have cut my electrical consumption by 2/3rds. The lights are perfect for reading in our travel trailer.

Great Replacement Bulbs for Motorhome
I bought these a while back and was waiting to see how they would work. Well they are great replacements for the 921 bulb. I bought eight to replace the bulbs over the sink and over two chairs. My wife reads paper books and on her ipad. She loves these LED bulbs since they don't glare on the books or the ipad. The same goes for my laptop. I will be buying additional bulbs to change out the entire coach. Get the LED bulbs, you won't be disappointed with the bulbs or the service from M4.

921 Replacement
Replaced all 921 bulbs in trailer to LED. What a difference in the light that is produced and no heat. The reduced amp draw will also help the battery. I want to personally thank M4Products for fast service, fast delivery, and a great price. Quality is top notch... Keep up the good work. Highly Recommend...

Upgrade interior lights to LED
I ordered warm lights for general overhead and cool lights for work areas. They look great! The cooler white light are very bright and will work great for reading while the warmer lights are easy on the eye for general lighting. I can't wait for the season to come around to dry camp and test the battery life. The converter charger doesn't run as much....very nice. I did have one of the CW 5050 bulbs start blinking right after install. Emailed M4 and they sent a replacement ASAP...no questions asked. It is pleasure to deal with a company that stands behind their product. Will be replacing running lights very soon. Thanks Guys!
