The water in my pond is starting to turn green with algae. My OEM Delta UV lamp (think Elektra) was about 1 year old at the time, around the time they recommend replacing it with a new one. I replaced it with a cheaper LSE bulb with the same specs as the original. A few days later the pond became clear again, which means the lightbulb should work. We hope that it will also provide sufficient performance for at least a year. I had to revise my estimate as this lamp failed after 3 months. The Elektra lamp that came with my Delta UV instrument lasted a year.
