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

This bulb is just as advertised. It is very bright and matches the color of the incandescent original bulbs very well. I have not used them long, but look forward to not worrying about how long the lights are on.

Excellent products. Shipping was very timely. Replaced some 921bulbs in RV and they are as advertised. Will replace other lights with M4 products.

Great upgrade from existing lights.

These are excellent replacements for the incandescent bulbs that came in my travel trailer. The color is very similar to the incandescent bulbs, but obviously use a lot less power. Also, they are at least as bright as the incandescent a, and the quality is very good. I had purchased cheaper bulbs online, but they were terrible (flimsy, four tiny wires as connectors, took several tries to get them working). But the M4 bulbs are very well built. No little connector wires, but solid IC connectors. The bulbs are also relatively heavy, as proof of their quality construction. I pushed the bulbs into the fixtures and they worked first time. No issues at all. I also got some "natural white" color LEDs. They are equal in quality and brightness, but a bit harsh for my taste. I found the warm white to be easier on my eyes. Finally, customer service was exceptional. I sent emails with questions prior to ordering and got quick, informative answers. Shipping was surprisingly quick too.

Love the light that this buld gives off. I was unsure what the light would look like, so I installed one in a dual bulb fixture, reall can't tell the 2 apart. Will be ordering more.

After seeing the reviews of this website and the lights themselves, I bought the cheapest ones I could find on that giant auction site anyways. I got a ton of lights for a dollar type deal. Well they suck. They were half as bright as a regular bulb so you had to turn on more lights. So I saved my pennies and bought these. These are almost the same brightness as the original, no where close to the same temperature. Those originals you can't touch after they been on for more than a few seconds. These are bright, run cool, and use a fraction of the power. Stop reading and debating what lights to get and buy them.

I purchased this particular bulb as a comparison against 2 different bulbs from the Elite Series - in part because I wanted to test the different color temperatures and to gain a sense of brightness relative to stated lumens. This particular bulb was picked to replace the bulb in the range hood light in a slide-in truck camper. Based on a simple test (we have yet to camp with the light) this bulb will work nicely, but I suspect the natural white might provide a better level of task lighting - which we'll compare to the Elite Series bulb. As I have a solar controller that voltage compensates for temperature, I especially appreciate the 30V rating.

I have placed several orders with M4 now. I don't typically write reviews...good or bad but these guys do an exceptional job so I hope this helps future buyers. I ordered 3200K wedge base LED bulbs and the color match to incandescent is perfect. Each time I have placed an order, it was received within a couple of days...like Jimmy John's of the LED world! I would highly recommend M4 for your lighting needs.

This was an awesome replacement light ove my range and in the shower of my class c motorhome. Snug fit was overcome with a little dielectric grease. Service was spectacular again as it was on my first order too. Looking forward to linger battery life while boondocking as i replaced all my rv lights with leds from M4.
