Review on Upgrade Your RV Lighting With Ultra Bright T10 LED Bulbs - Pack Of 10, Pure White by Mandela Buycks

I wanted to replace all the incandescent 921-style bulbs in my camper with LED. After reading reviews I ordered three different kinds to try out. I was blown away with how bright these were, especially considering how little energy they use. Another kind was much dimmer but drew only slightly less energy. The third kind were a tiny bit brighter but pulled almost three times the energy. My original incandescent 921-style bulbs draw 19 watts (255mA @ 13.6 volts), which is the typical voltage that your camper's converter will output. These are every bit as bright as the incandescent and they only draw 1.5 watts (113mA @13.6vdc). The color temp was everything I had hoped as well. Cheap LEDs are often very cold, but these are a great balance between harsh blue and overly yellow. Also, they all worked, which isn't always the case with super cheap imported LEDs. I just ordered another bag!
