i will ditto's John commet with the T-5HO it do kick butt with alot of light and yes it did save alot of engery on this one and right now if i am " hearing " this one is the POCO is setting up a rebate some say 75 buck and some saying 100 buck rebate for high bay lumiaires.
i did put few on for demo wow you should see the comuster reaction they just about drop the jaw to see how this flourscent lumiaire do kick out that much light level.
i have few orders line up but have to wait for poco to catch up with rebate it going like nuts here now with higher cost of electric rate[s] they will keep going up anyway
they start pretty fast as well but work pretty good in very cool spot but just take a min or two get warm up after that it work fine and they have instast restrike so i dont have to deal with " dirty quatz " bulbs at all
Merci, Marc
