水草情迷

10000 HOHRS, however, how about the decreasing rate of lumen, e.g. PHILIPS TLD SUPER 80, 4000 Hours decrease not more than 10% LUMEN.

Dear tam and everybody,
Just a few questions want to ask about the Philips PL light:

1. About the "philips green box 3 coil PL light" - is that the one that can be brought over usual light shop, with normal 'big screw' base for usual home lighting?

2. Please share your experiance about using it for grass tank. Is it OK for grass growth.

3.Lastly, do you use the 'daylight' type (as there are a few choices about the color) and do you know how many K is it.

thanks a lot. Just for sharing.
