|This T36 style, 12v LED tube light is for 36" fixtures typically found in the kitchen ceiling of an RV. Our LED tube lights will work with the ballast removed and they are rotatable, so you can aim them in whatever orientation that works best for your lighting needs. They are frosted tubes so they look identical to their fluorescent counterpart that you are replacing. This is only available in 6500K. These tubes are polarity sensitive. One Year Warranty.
