Hi all,

Everybody likes good lighting I'm sure except I have few needs.
Replacing the old fixtures.

Have to be electronic ballasts. I get tired from 60hz exposure and
sore, dry eye. Good CRI at least 80+. Color temp between 3500K - 4100K
but I could use "Sylvania's sunshine" (Phlips C50) which is about
5000K and would like to know your experiences with these.

But the store I visited was told about law in ontario canada says can
only get 32W maximum for F40 length (4 foot) and higher for F96 (8
foot) but I think this is bull?

I rather take 40W fluorescents since the type of bulbs I'm looking for
has the specs I want.

My current set up as now over my bench is 10 feet ceiling with old 2 x
4 foot fixtures, each fixture has 2 bulbs. Next to it is one twin
bulb F96 (8 foot).

For close work, ideas on using incendscents lights to light specific
areas?

Cheers, Wizard


Actually 40W tubes are legal at the moment, but only in the premium
phosphors, not the old halophosphate stuff (CW, WW, etc) though far less
efficient incandescent stuff has regulations at all thanks to the usual
beaurocratic nonsense that makes up our largely useless energy laws. The
thing is, few "40W" ballasts run the lamps at anywhere near full power, so a
pair of 32W T8's on an electronic ballast are actually considerably brighter
than a pair of 40W T12's, plus you get no flicker. You can even get ballasts
that overdrive the lamps if you need more light, but it's easier to just use
more lamps and cheap T8 ballasts you can get at a hardware store to run up
to 4 lamps each. Personally I like F32T8/850's, 86 CRI 5000K, nice bright
clean white light.
