Hard to find product
Great experience. No one else had the UV lamp I needed for my sanitization system. I was skeptical ordering from California when I'm in Canada but the product arrived fast and trouble free. Great service.

Excellent replacement
Packaging excellent. Provided protection to the bulb. Would have appreciated brief instructions re: installation. Do I need to ensure glass tube is dry inside? Reminder to install plastic "bumper" on bottom of lamp. Reminder re: connecting plug....it will only fit on 1 way.

Hoping for long life. Stay tuned.
