Hi Dusty!

You really think the heat will be a problem?
If I put tray filled with water, will it be ok ? About 1 fan on each
extremity of the shelf?
How hot can it be?

I`m also thinking recovering 3 side with plastic to increase humidity level?

Thanks

Claude

I put a picture of my set up in alt.binaries.pictures.orchids with the

I forgot to mention that lowes and Home depot carry the fixtures.

these fixtures will attach to shelveing but you may have to drill a screw
hole.

Cords that's easy my local computer junk store has baskets of computer
power cords for $1 each I cut off the end that goes to the computer and
strip the outer covering back three inches wiring is with wire nuts black
to black white to white and green goes to the lamp housing under the green
screw. If you get a Eruo cord then its brown to black blue to white and
green with the yellow stripe under the green screw. There are knock outs at
the end of the fixture and you will need a wire clamp/strain relief ask
where you buy the fixture. Make sure there is no exposed wire pop the cover
back on and your good to go.

I sure hope I'm not confusing you more.
Dusty

Sorry about the incompleet post but MSN has a nasty habit of dying and
somehow posts an incomplet message.
Dusty

Thanks Dusty! I see the pink isolation foam! That`s a good idea!

I`m not confused anymore :-)

Thanks

Claude

Maybe we're talking about different 32W bulbs...

I checked the specs on some a while back after making the same higher
wattage = more light comment, and found that it wasn't correct for the
bulbs in question.

Don't ask what they were, I simply do not recall.

Here's what I found
what the spec sheets say
Starting lumins for a F40 T12 lamp is 2900
Starting lumins for a F34 T12 lamp is 2900
However putting the two fixtures together and looking at them from a
distance the 40 watts apear brighter to me but then my eyes might be
biased.
starting lumins for a F32 T8 lamp is 2800

I have no idea how they measure lumins
I'll have to do a google search on that.

A fixture with magnetic ballast consumes about 1/3 more input power than
one with an electronic ballast. The extra power translates directly
into heat, so if you're concerned about temperature of the shelf above
or simply want to save energy you should consider an electronic ballast.
An additional benefit of electronic ballasts is higher light output.

A good summary of fluorescent energy use:

And here's a fluorescent FAQ:

But which phosphor are in those bulbs? That makes as much of a difference as anything.

The best information that I have on phosphors is that they have more to do
with light color than light output. There is a way to increase the light
output of a 40 watt lamp and that is to increase the surface area of the
lamp it's self. Worms way sells such a lamp, it has groves in it but I
don't believe it is cost effective.

There is another way to get more light in the same area and that is to use
a 48 inch 60 watt fixture. they look just like a 40 watt fixture but the
lamp contacts and ballast are different However they are very hard to find
or require special ordering from an electrical supply warehouse.

John is correct in saying that a fixture with magnetic ballast consumes
about 1/3 more input power than one with an electronic ballast. This is
true only if the ballast is commercial / industiral grade. The others
either eat lamps or fry themselfs within a couple of years. Also note
magnetic ballast being sealed in tar are splash proof but electronic
ballast are not. I'm not saying you can flood any fixture but drips happen.

Most of my units are magnetic ballast because of the low initial cost
(free) from demolition dumpsters.

Now my brain hurts because it has run out of answers.
