Sturdy, adequate light, impressed so far
My final opinion will be formed long from now after I've been able to access the reliability and longevity of these LED's but rating them immediately after purchase and installation, I am impressed so far. They are bright, well built and easy to install.

Good Product / Great Service
The LED bulbs work and look great in our RV. I was most impressed with the service of M4Products.com. My order was delivered in two days and was accurate and well packed. Unfortunately, one of the ten bulb order did not work. These things happen. I contacted M4 via email and Steve sent me another one right away. Just terrific customer service. I will use M4 again.

921 LED Warm White LED
No one can beat this price!!!!! Also, when comparing others - look at the number of LED's - this product has 24 SMD chips, which is the largest I have seen for a 921 replacement - most companies have 18. The Warm White - to me is around a 3000k or higher temperature, and could have been 2700k and less to look more like an incandescent bulb - the Cool White would be too fake looking for the interior of an RV - exterior would be OK.

OUTSTANDING PRODUCT AND PERSONNEL
Purchased these lights on 11-7-12 received them on 11-9-12 , I had no problems installing them and all work instantly without a flaw. Great led lights for the price and they make the inside of my rv look great as well. The personnel at M4 LED were great as well, they helped me pic out the right led lights for my rv and their input was OUTSTANDING. I would and will recommend this company to anyone and everyone.
