Does anyone make true 8' long flourescent light fixtures in a T8 bulb
design with electronic ballast?
All of the 8' long T8 fxtures I have seen to date actually have four 4' T8
bulbs instead of 8' bulbs. I want electronic ballasts to reduce the hum.
Try google - I searched for T8 8' and the second link was
http://www.nam.lighting.philips.com/us/ecatalog/fluor/pdf/p-5029c.pdf Its a
PDF, deconstructing the URL a bit takes me to
http://www.nam.lighting.philips.com/us/ecatalog/fluor/ with another 8' T8
That should get you started.
I've found the fixtures are available from Grainger and verious online
places, but they cost $60 to $70 plus shipping versus the Home Depot
fixture with four 4' bulbs for $40.
I never thought about bulbs and didn't look at what HD, Menards, etc
carry for bulbs. The bulbs are available at Grainger for a premium price
Most of the shop lighting threads I have seen say to use 8' fixtures
instead of 4' for better lighting. I wonder if the 8' fixture with four
4' bulbs would work just as well? There is no way I will consider using
Just go to your local commercial lighting supplier, T-8's are required
in new commercial buildings in most jurisdictions due to their lower
energy use and mercury content. I use T-8s everywhere these days...
Almost all fixtures designed for T-8 bulbs have electronic ballasts.

They're fairly easy to find around here, but ... you usually have
to ask for them. Check your lumber yard and local electrical
supplies; they should have them.
They seem pricey at first, until you realize that, with 4 8'
tubes, you're also getting two ballasts and cktry for them.
As far as bulbs go, well I see those all over the place including
HD and Lowes, True Value, etc etc etc..
I use them in my shop; great light output and it spreads over a
LARGE area too. I pull the mains wiring for the ballasts out and
put two switches to a light fixture so I can have "decent" light
with two bulbs, or "excellent" light with all 4 on. Mixed with a
Halogen, they're perfect for finishing work - the dings & dangs
stand out like a big orange box!
Be sure they're not too much light for you though. My Mother had
eye problems so I put one in her little kitchen when she was
alive. She loved it. But it's too bright for anyone else.
Point is, if it's a small area with standard ceilings, leave
room for one or two smaller fixtures for "just passing thru" use.
Saves on 'tricity too. Ymmv
Interesting. All of the 4' four bulb fixtures I've seen just have one
I'm not real sure I would want a fixture with four 8' tubes. That would
seem to be too much light in one spot. Wouldn't it be better to use 2
bulb fixtures more often to spread out the light?
I am very concerned about costs of running all the light people recommend.
1500 watts of light in a 24x24 shop run a few hours a day could really add
up along with all other electricity used in a shop.
Yes they make them, but they aren't destined to be an industry
standard. Most popular for use in commercial applications now would
be the newer T5 HO systems, or using the 4' T8 lamps with a high
output electronic ballast.
What exactly does high output gain you? Does it just pump more watts
through the same bulbs?
I see a lot about T5, but no DIYer is going to pick these up at Home
Depot, Lowes, or the like.
No you probably won't, and for a home shop the 20% extra from a high
output ballast probably isn't worth it. Do check the Ballast Factor
on the fixture you get, as not all ballasts are created equal, and
higher ballast factor will get you more light. If you getones that
have an Advance, Triad or GE or major manufacturer electronic ballast
they will have a 5 year warranty.
My local ACE hardware has 8' T8's, I will ask them this weekend if
they are electronic ballasts and what the brand is. It seems to me
that most anything new uses the electronic ballasts, the local ACE is
only about two years old.
