I needed to change the lightbulbs in my main sink faucet. After testing LED bulbs at my local department store, I found a much better deal at Revain. I bought a pack of 12 (needs 12 lights) and they arrived earlier than promised. I found that one of them doesn't work right out of the box. I emailed the company and they immediately sent me 2 replacement bulbs. Excellent customer service! The LEDs are pretty bright, I could swap the switch for a dimmer and since they're dimmable I probably won't need to change bulbs for a long time.
