Review on 🔆 GRV T10 921 922 912 LED 38-2835 SMD DC12V 3000K RV Ceiling Dome Light RV Interior Lighting Trailer Camper, Dimmable Warm White LEDs, 10-Pack by Ross Bagby

Last year we bought a set of these LEDs for our RV. This year we upgraded our campsite to a Class C RV. One of the first things I did was remove the light bulbs and replace them with these LEDs so I had to order another pack. The performance of these lamps is ideal for a motorhome. They are bright. Brighter than the bulbs they replaced. More importantly, they are much more energy efficient. The lower wattage can really make a difference when traveling inland where the only power sources are a battery and generator. original 5 star rating. At the last location we had no cable and it was interesting for us to see the opening ceremony of the Olympic Games. We switched on the antenna and aligned it for reception. We had a strong signal and enjoyed watching the event. until we turned on the light that had one of those lamps in it. Immediately the TV picture froze and the screen went dark with the warning "WEAK SIGNAL". At first we weren't sure what happened. But then I decided on these LED bulbs. After we turned off all the lights, the signal returned to the TV. We have lights that use LEDs from other manufacturers and do not cause TV interference. We even tried different channels thinking that maybe they only affected that particular channel but it wasn't. Apparently they emit enough RFI to destroy any channel they could possibly receive. I have access to a spectrum analyzer and may do further testing and contact the manufacturer to share my results. One of the things I particularly like about these replacement bulbs is their color temperature. I'm not talking about heat, but since I'm there it's important to note that they generate little to no heat compared to previous incandescent bulbs. Color temperature refers to the color of light. Cool light tends to be bluer, while warm light is more yellow. Ironically, Kelvin (K) numbers are a little behind the times many people think. A higher number like 6500K is bluer and a lower number like 2800K is more yellow. These lamps seem to offer a very good balance. One of the reasons you like warmer light, especially in an RV, is that bluish light tends to attract more bugs. It is very convenient to read and work under them. We only put one bulb in some of the twin lights in our trailer because they were bright enough. The bathroom had 2 double lights and it was too bright with 4 of them on at the same time. The new camper has two lights with switches for each lamp, so you can conveniently turn on a lamp or two when needed. One of the things we looked for when choosing a replacement bulb was the presence of a voltage regulator circuit. You'll see this listing from 12v to 28v. This means they can handle voltages over 12v which can happen in an RV while charging or if you have a cheaper converter. LED bulbs generally last longer than incandescent bulbs and are much less susceptible to vibration. Time will tell how well they hold up and I'll post an update if anything changes.
