The technical aspects are that there are multple lights spread out
lengthwise so that the entire table is lit. As I said originally.
Your only alternative (to spread the light evenly) is to raise what you
You can use any bulbs you want
re: "You can use any bulbs you want"
Well, yes, he can use any bulb he wants, including red or green or
multicolored flashing stobes, but using what he "wants" doesn't always
equate to using what's "best".
Of course, no one would go to the extremes I mentioned above, but the
type of light that different bulbs emit can certainly make a
difference in the clarity of the balls, the contrast between the balls
and the table, the contrast between the rails and the pockets, etc.
The optimum balance between all of those items could very well result
in more shots made as well as less eye strain during play.
I seriously doubt that when a championship table is set up for those
TV shows, they hang the lamps at the proper location above the table
and then just go into the janitor's closet and grab any bulbs they
find lying around. I'd be willing to bet that they have done research
and experiments and have come up with a specific type of bulb that
There isn't a lot of choice, derbyOH...
Anything else? I'm betting on incandescent. And about the only choice for
those is wattage and frosted/nonfrosted. True, you can get them with
colored glass but only an idiot would consider them for a pool table.
Unless it was Christmas.
I didn't think so. So why are you pushing back on my suggestion that
he contact an "expert" and ask them what they recommend? If different
bulbs will make the table "look" different, why not ask someone who
deals with it every day?
Isn't that why people post questions in this NG? Don't they do it to
get recommendations from those in the know? Well, who knows more about
pool table lighting than someone who lights pool tables for a living?
Because it simply isn't rocket science. OP thought his table was
underlighted. The solution is to increase the light. One increases the
light via higher wattage bulbs or by adding fixtures.
Different bulbs won't make the table look different; different light sources
may but that difference will be subtle, his eyes would adapt to it and the
difference would only be from sources he is unlikely to choose with the
exception of flourescent.
As I said, it isn't rocket science so why turn a simple problem/solution
into something complicated? I really don't care if he contacts a whole
*FLOCK* of experts, just seems silly. At some point, people really need to
think for themselves and exercise some common sense.
FWIW, HTH & HAND
Did you read Tomsic's response to your post? There's a lot more meat to
that response than simply saying "raise the fixtures and put in any bulb
I suspect that Steve was looking for the type of details that Tomsic
provided. Not rocket science, illumination science.
Yes, I read it. There was more meat in my *first* response to Steve too.
Including foot candles. I didn't dwell on foot candles because it is
unlikely Steve would have any way of measuring it; the simplest way to
handle it is to simply increase wattage and/or fixtures until the intensity
Tomsic's main thrust was "providing a suitable amount and distribution of
light on the table along with good color". Same as my first post.
He suggested a 4' fluorescent. That would give decent coverage; however,
all fluorescents are deficient in red; that might or might not bother Steve.
It would bother me.
If Steve is not inclined to buy another fixture(s), raising his current one
will increase the coverage; it will also diminish the light intensity at the
table surface; ergo, increase wattage. An option I suggested originally.
So you think a salesman or CS rep at a billiard store is going to be versed
in the physics of light? hehehe
As long as we're bringing up past posts, early on I replied to Steve:
"I've often found that the CSR's at many companies can connect you with
people that actually know the technical details about the products they
sell...stuff that isn't available on their website."
Let's drop it, OK? You've made your point.
Seems like the answer to the question initially raised depends upon what the
pool players are trying to see. Then the problem will be to try and avoid
such things as glare while providing a suitable amount and distribution of
light on the table along with good color.
My experience with lighting such relatively small, shiny and moving objects
is that at least 40-60 footcandles (lumens/square foot) are required. The
light should be diffuse (no bare bulbs) since they cause multiple
reflections and shadows that could affect the aim of the pool cue. There
should be some ambient light in the room so when the players look from the
bright table to other things in the room, there isn't a lot of light/dark
contrast. That tires the eyes as does trying to look through glare.
A simple solution would be a 2-tube fluorescent fixture which uses 48 inch,
32 watts/tube T8 lamps of good color shielded with a white plastic 1/2 x 1/2
x 1/2 inch cell louver underneath. If the louver is too bright compared to
the pool table surface, spray the room side of the louver with a gray or
dark color paint. If you want to use incandescent or another kind of
screw-in bulb, look at fixtures such as: http://alturl.com/wgdjr With
three 150 watt incandescent bulbs, there will be about 1/3 more light than
with the two 32 watt fluorescent tubes -- and more shadows -- and the
fixture is more costly; but you can easily dim the bulbs with a wall-box
dimmer or use lower wattage bulbs.
