Correct. Most recommendations for t5 bulb replacement assume 10-12 hours of the bulbs being run a day. If you use them to supplement and not acheive the no shading period during your peak light, then no need for a year being the time to replace.
365 day year w/ 10 hours a day: 3650 hours
365 day year w/ 4hours a day: 1460 hours
So for giggles, lets say 3500 hours is the life expectancy of the bulbs. That is about a year at 10 hours. 2 years at 4 hours.
ahh the light build just came on ;Hilarious Just run the T5s at the 4 hour peak.That's how I read it.
