💡 10-Pack Super Bright 921 LED Bulbs for RV, Camper, Trailer, Motorhome, Marine Boat Dome Interior Lights - Natural White 3500K Review

I tested the foot candles of two lensed incandescent bulbs in our caravan. With lightbulbs they were 6 foot candles. After replacing the lamps with LED wings, the output tripled to over 18 foot candles. The color of the LED lamps is bright white. See attached photos. I've used 19 out of 20 and they all worked well. I hope this helps if you're looking to replace incandescent bulbs with LEDs.

I can only say WOW! Doesn't matter! When we bought our RV about 5 years ago it had regular glass bulbs which didn't disturb the light much and shortly after that one of our covers melted. I immediately bought round LEDs and replaced all the bulbs in our trailer. Although they ran a lot cooler and threw more light, they also looked a bit dim, but better than glass. When I pulled into a friend's van the other day, their lights were so bright I asked them what kind of bulbs they were using. I…

Surprising improvement over cylindrical bulbs. We'll take the device out of service for a few days and have time to evaluate long-term performance. All LEDs are directed downwards from the fixture and are not omni-directional, so useful light is projected into the illuminated space rather than onto an inefficient reflector. Old bulbs on the left, new ones on the right. Barrel shaped contact wires are also problematic as they are often too long/short and misaligned. After a four day vacation we…

For the past five years I have tried various LED replacement bulbs for incandescent bulbs in my RV with little success. They were either not bright enough or didn't work reliably. I was just about to reconcile the fact that I would live in a dark RV all the time when I decided to give it a try. Since the description sounded promising, I immediately bought a pack of 20. I put 1 of each of these LED bulbs in three 2-bulb fixtures to get a side-by-side comparison between the old and new bulbs. As…

When I first opened the box, I was concerned because all the "light bulbs" were shaken out of the box (not opened), so I was afraid of damage. However, I used 18 out of 20 during installation and they all worked 100% - no crashes or dim lights. The PCBoard material for the pins is a bit tricky to install as the edges are sharp (compared to smooth glass) but they got it all installed. Some of them had to be adjusted as contacts were not being made, but with a wiggle/movement they all turned on…

Bought these to replace the halogen lights in our RV. I was very concerned that they would be too white (those painful blue and white ones, like in a hospital). But despite being brighter and whiter than halogen, they were still warmer in color. Plus they are BRILLIANT! I bought these to reduce power consumption and extend battery life in our RV. BUT they are far from perfect. Halogen lamps were more stable. They do not "flicker", but dim when the battery is additionally loaded. The water pump…

I first replaced all the incandescent bulbs in my RV with LED "panels" which were large and took the place of the regular RV lights and double used were tape to attach it there. Well they worked great for over 5 years but then I noticed the color of the light changing from a beautiful warm amber to whimsical shades of red, pink, green and even purple in some cases. So after 10 years. and with more and more falling into fancy psychedelic colors, it was time for something new. I decided to try…

In contrast to many replacement LED lamps, they do not have a switching power supply. Instead they appear to have multiple groups of diodes arranged in a current mirror pattern. If you're looking for quiet bulbs that don't produce all kinds of RF noise, these are the bulbs you *need*. The tubes have a full wave rectifier built in, so they are non-polarized (so you can wire them either way and they'll still work). These lights work in a very wide voltage range from less than 11V to over 14V…
