I love my lightbulbs and they work well. No degradation in illumination. It is pretty blinding, but it's definitely what we need.

The advertisement says not dimmable. You have to unscrew them and put them into the included hook for them to turn on. Bulbs are in lamps but do not light up when power is off.

Volts are a must for an rv. Running 12v ac is a lot easier and safer than 120v lines. Ideal for off grid, solar dc application.

The bulb is super bright! I like the color (not lewis) the brightness, though i would’ve preferred 5 w bulbs that were a little dimmer. The light is a more natural albeit yellowish hue but a welcome change from the bright led bulbs in other fixtures.

Only two out of the five work at full brightness. Poor longevity. Do not buy.
