921-24-5050-WW Warm White 5050 SMD Light Bulb with Wedge Base

Made purchasing my LED bulbs easy. Learned a lot about LED's when using the site. Learned that I best use the warm white color in my RV to create soft color. Great service and prices

super delivery time / easy install. I struggle with the traditional white/blue led "glare" I. e. (one of my automotive droplights)- my wife hates it. these are pleasing nice warm, but bright light. reason for 4 stars-- my R.V. uses 9 so I have an extra. if I don't need it for a long time it'll be 5 stars!

shipped on time ,easy install, they're not the cold blue light that we were afraid / hard to tell from the 921 that we replaced. we're looking forward to the battery savings and life promised-all is well

Only got 2 bulbs to start with, installed in center of the trailer. And tied to use mainly these bulbs, after 4-days 3-nights dry camping battery level would bounce between 3 to 4 light level good-charged. But after 1st night 1 bulb was out, removed it and turned it over? Worked good the rest of the time? M4 Note: This type of bulb has a plastic base with wires that wrap the bottom. Ensure the wires go straight up the base and pull them slightly away. It probably was just not getting a good contact in the socket.

VERY happy with these bulbs! The quality of bulb construction was immediately evident. They are just a tad brighter than the 912/921 incandescent bulbs I had in the camper originally. The color tone is also a tad whiter compared to the incandescent's noticeable yellow hue. My fixtures used to get really hot with the incandescent bulbs. They now stay cool with these LEDs. Shipping was also extremely fast. Great product! Great company!

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-WW Warm White bulbs put off a nice warm, natural light over our dinette and in our living area while producing zero heat. Great customer service, fast shipping, and a superior product. We will order again when we finish our LED retrofit.

I have done a lot of research on different LED replacement lights for my RV and decided to try M4 brand of lights. I purchased the 921 warm white bulbs and was very pleased with the color of the lights compared to my existing RV lights. They are very close to the same color and brightness. I would defiantly recommend these lights to anyone looking to upgrade the lights in their RV.

I am completely satisfied with this product. This warm color bulb used the th bathroom.

The "Warm" Color worked best for us ... very similar to the incandescent bulbs, maybe a little brighter. And of course, a lot less heat and power usage. Delivery was very prompt.
