Review on GRV Ba15s 1156 1141 LED Bulb 4W 56-2835SMD Super Bright AC/DC12V-24V 40W Halogen Replacement for Interior Lights in RV Trailer Camper Motorhome - Warm White (Pack of 2) by Jerry Eintertainment

I just installed these in a 22ft toy tractor/RV and they are definitely better than the 1141 bulbs that came with the RV. All 10 in the kit worked fine (every LED lit). They are definitely brighter than the 1141 and pretty much the same as the 1156 without the extra power and warmth. The color is a little whiter than the 1141 which is nice as the 1141 bulbs are a bit yellowish. Each light source has a constant brightness and color temperature, which is a common problem with cheaper LEDs. These bulbs are rated for 11-28 volts, which means they contain some sort of internal voltage correction and can control the power of the LEDs. Most cheap LED bulbs only work over a small range of voltages and will burn out if your RV's converter goes above 14 volts. They seem a little expensive but they are a good buy. Two of these bulbs cost twelve dollars, 10 out of fifty will save you a dollar on light (I needed 14 for my RV). The added cost is worth the peace of mind of not having to worry about overloading the LEDs and burning them out. I will update this review if anything changes. I'm definitely looking forward to the extra dry camping time I'm gaining as flashlights have been my biggest craving for batteries.
