I'm looking into future lighting considerations, prompting the following:
Not having any background in either EE or office building facilities, I looked
at the listing of electronic ballasts in the online Grainger catalog (
http://www.grainger.com/cgi-bin/ecat2b?13386663:125 ) and couldn't make heads
nor tails of exactly what was being offered.
I know that I want a 4 tube ballast that will work with T8 tubes, but I also
want it to work for my current T12 tubes. The prices are really nice, with
none of the 4 tube ballasts over $60, and most of them not over $45. I'm
looking at the following parts:
BLST-(4)FO32T8, 120V 75% LIGHT OUTPUT
4/17-32W BLST R/S 120V 4 LAMP 17-40W 120V RAPID START REDUCED HARMONIC
BALLAST
4/17-40W RH BLST 120V I assume this is a reduced harmonic ballast too.
4/34-40W R/S BLST 120V 4 LAMP 34-40W 120V T-12 RAPID START BALLAST
(expensive)
What I'm not certain of is that any or all of these are electronic ballasts,
and what the reduced harmonic means or the 75% light output means. I have this
feeling that I don't want to have anything to do with a ballast that advertises
75% light output as opposed to 100%. Only one was marked as a T-8 and one was
marked as a T-12. There were also a number marked as T-5 and I haven't heard
any talk of that type of tube on this list. Also, some were marked IC and some
were marked CIC; what are these? Some of the ballasts were marked as dimming
ballasts. Do they just kill one light at a time or do they actually dim a fl
tube?
Anyone care to explain to me what I'm looking at here?
Thanks,
