Great Upgrade!
First time customer: I changed from the original incandesent 921 bulbs to the warm white LEDs. Made a world of difference in our somewhat dark trailer. The service from M4 was quick and friendly. Even though one of the bulbs failed shortly into the first hour of use I was pleasently surprised to receive a replacement (without hassle) within 4 days at no cost. I appreciate the time taken by M4 to explain some of the technology that surrounds the LED vs incandesent color and brightness levels. Very helpful!

new bulbs
bought 14 led bulbs had 2 bad and they replace them both right away. very happy with them lumes are great just as bright as the regular bulbs. we had in the r v M4Note: The defect rate is about a quarter of one percent on these, so two in one order is very rare, but of course can happen. Apologies.

Bright in the RV
Awesome product,super fast FREE shipping & customer service second to none. Need I say more? Well the other night I turned on a light in the house & said "seems dim in here!" I have been spoiled by these lamps in the RV!

LED changeover
Wish I had done this years ago. Lighting is great and power consumption is way down. Now we can leave some lights on and not have to worry about the batteries.

just received
Will be trying them on trip Oct 9th.

best replacement lights
Really like the soft warm light without the heat and power consumption. Am planning on buying more to replace all the lights in our Rv.

Just what I wanted!
The warm white light is 50% brighter (just what I wanted) than the stock #921 incandescent bulbs in my Jayco travel trailer and just the right color light.

Nice warm light
Every one of the LEDs worked right out of the package. It was very easy to replace every bulb in the RV. My wife liked the color temp of the bulbs. When she is happy, I'm happy. Thanks for the good product and service.
