💡 GRV T10 921 194 5050 SMD LED Bulb Lamp Pack of 10 - Super Bright Cool White DC 12V Review

I use these in my motorhome which comes with #921 bulbs in all interior lights, there are 28 in total. I bought 10 of these for the first time and have been very pleased. The color and brightness are very close to those of incandescent lamps. The change was easy and all LEDs worked perfectly. I ordered a second set of 10 units and am now ready to order a third set of 10 units to complete the upgrade. They use much less power (1.5W vs. 18W) and generate less heat. We like to go on dry hikes (no…

I am so happy with these bulbs. We just bought a new trailer (well, new to us, but a used 2013 Jayco). It had standard 12 volt "921" light bulbs. I wanted to replace them with LEDs for two reasons. turn the electricity down when we camp unplugged and 2. they run cooler which means less heat in the caravan in the summer and also prevents my kids from burning themselves on the ones next to the beds. This is the perfect replacement. The color temperature is actually perfect for a standard RV lamp.

I bought 20 of these bulbs to replace the bulbs in my trailer. At $2.33 each, it's a bargain, especially compared to what RV companies charge for it (about $10 each, IIRC). Each worked 100% as advertised. They are about the same brightness as the OEM bulbs they replaced, the color tint is so close to that of incandescent bulbs that it's impossible to tell them apart unless you compare them side by side, they emit little to no heat and consume about 10% energy. . . I don't know, LED bulbs don't…

I rarely give one star reviews I normally give two stars but in the case of a product that may actually pose a safety hazard I find it necessary. However, if you look at the fine print, there may be wording to suggest looking for compatibility in terms of voltage etc, but it's not advertised enough for the consumer to make an informed choice. In short, they overheat when your RV is plugged into shore power. This is because battery power is limited to 12V, which is what they are designed for…

Short/simplified description of LEDs (no technical details). The LEDs themselves do not interfere with radio/TV signals. The voltage regulator in some lamps causes interference: this means if the input voltage has a range (e.g. 8-24V or similar) there is a good chance that you will have interference on certain signals. On the other hand, a lamp with no input voltage range (12V or similar) has no regulator and will not interfere with certain signals. Although 12V DC may not always be available…
