The brightest bulb this size.  For its smaller physical size (smaller size than original 912/921), this Super Bright 5630 SMD LED bulb packs a punch.  It has a full aluminum body, is slightly smaller than a 921 incandescent, yes produces a little more light.  If you want a an even brighter light, look at our larger 921-17-5630 Elite Series Wedge LEDs.  This is part of our Elite Series of bulbs.  The PCB base also makes great contact on the first installation.  Be sure to browse all of the pictures on this special retrofit light!

This is Cool White which is brighter than Natural White. 

For Natural White see part number 921-10-5630-NW and

For Warm White see part number 921-10-5630-WW.

  1. Very satisfied M4 lightbulbs 5 Star Review

    Posted by on 7th Apr 2019

    This is our second order of 921 lightbulbs from M4. The first ones have been in for almost a year and we are very satisfied with the brightness and how cool they are when on. We are in the process of replacing all of the old bulbs with leds.

  2. Bright Light. 5 Star Review

    Posted by on 25th Mar 2019

    Great replacement bulbs, a bit brighter the LEDs I'm replacing.

    Love the bonus M4 drink cosy that came with the shipment. That works really well too!

  3. review of this product in my motorhome 5 Star Review

    Posted by on 14th Mar 2019

    I really like these lights, they are bright white which helps me see clearly without having to put on my readers. The savings on power drain from the battery also make good sense to me.

  4. made several ourchases from M4. very good service and product. 5 Star Review

    The only place to buy led lights

  5. just what I was looking for 5 Star Review

    Delivered quickly

  6. Bright, but blue in color 3 Star Review

    Posted by on 16th May 2018

    Got this as a replacement for all my trailer bulbs. During the day when I tested they looked great. Went camping and turned on the lights at night and everything in the trailer was bathed in blue light. I had trouble seeing clearly....looked like I had a black light on because everything white in the trailer looked light purple. My mistake for not testing a bulb at night so I cannot return. Will order another temp bulb to test. Love that LED uses less energy because we camp without hookup.

    M4 Notes: Color choice is a personal preference; we do offer two other colors. We do ask that customers try one per sku for color and output before installing them all, but work with customers all the time to get them the right product. Kirsten did not reach out to us. Some love Cool White, some do not, it is our goal to provide as much information as possible so the customer can choose the color they prefer. The product was not in error, the color is correct per our Color Range Page, this just did not meet her personal preference.

  7. amazing 5 Star Review

    Posted by on 1st May 2018

    Bright cool white light excellent for closer proximity to your eye sight like overhead of bed or sofa. Steve was wonderful guiding me and explaining the difference between the 921- 10 vs the 921-17. So I could make an informed decision. Great illumination. Our old light was incandescent warm but it was glommy. I was afraid to buy these bulbs and color would be blueish. But they are not. Great for reading magazines, books or cell phone. On the other hand originally I had ordered 3 but only needed 2, so I called Steve and he made the change in the order before it shipped out . Talk about service!

  8. RV retro fit interior lights 5 Star Review

    Posted by on 16th Apr 2018

    Purchased this product hoping that we were making the correct purchase. Received product in a timely manner and put in the twelve lights ordered and as directed by paper work. Noticed right away that the lights were brighter then the market bulbs. So far we are very pleased with the lights and their performance. Like the idea of using less wattage and creating less heat.

  9. nice light... too cool 4 Star Review

    Posted by on 31st Jan 2018

    Nice light... but too cool for me. Unfortunately, I can't "try out" different lights and return them to see what works. Instead, I have to buy one-at-a-time to see what works and what doesn't. That's a pain - but there is no "rental" or "try before you buy" program :). Thus I'm on to order #2, to see how they work.

    M4 Note: Steve, there is not rental program, it would be too hard to manage. We do allow a customer to open and try one package per SKU though so test it for color and output, and that item is returnable. We just ask that multiples of each sku are not put into use, because nobody wants to buy returned used items. So you could buy one of several, determine what you like, and return the others.
    Normally though, after reviewing the Color Range Page with Pictures, and talking to us, we can narrow your choice down to one or possibly two choice that meet you needs. Full detailed shipping and returns terms can be found on the site. Call us when there are questions.
