I'm currently using 3 100w large globe type incandescent bulbs in my table light over my 7' table but they generate a lot of heat in a small room after being on for several hours and I was thinking about switching over to LED bulbs. Is anybody using the LED's and if so which ones, how many lumens and what color temp. would be best? Also do they operate significantly cooler than the incandescents? Thanks.

I had one of the 5000K 2 x 4 LED panels off of ebay. I hated it. It made my eyes so tired. I held a grate up to it (from my Brunswick light), and it was way better. I got rid of it, and put the Brunswick light back up.

mine are diffused as well so none of that happens to your eyes
I'd have to see one of yours without the light on in order to see the diffusing. The ones I got on ebay, look exactly the same as the ones all the pool players are selling here on AZ, with the built in diffuser.
The "grate" from the Brunswick light was a grid of squares, about 1" length and width, and 1" deep. Significantly different than the diffuser built into the LED panel.
Again, this was just my experience. I know most people have been extremely happy with theirs.
I hear ya, each of us has our own individual needs :thumbup:
some people want 2 of my 2x4 panels for a 9ft table, 1 is enough FOR ME on my 10ftbilliard table
and those who have played on it didn't feel it needed a second

You guys should study what causes light to become polarized and what effect polarized light has on all nonmetallic smooth surfaced objects ...

Effects of polarized light string smooth non metallic surface
Laws of reflection
An example of the law of reflection
Main article: Specular reflection
If the reflecting surface is very smooth, the reflection of light that occurs is called specular or regular reflection. The laws of reflection are as follows:
1.The incident ray, the reflected ray and the normal to the reflection surface at the point of the incidence lie in the same plane.
2.The angle which the incident ray makes with the normal is equal to the angle which the reflected ray makes to the same normal.
3.The reflected ray and the incident ray are on the opposite sides of the normal.
Mechanism
In the classical electrodynamics, light is considered as electromagnetic wave, which is governed by the Maxwell Equations. Light waves incident on a material induce small oscillations of polarisation in the individual atoms (or oscillation of electrons, in metals), causing each particle to radiate a small secondary wave (in all directions, like a dipole antenna). All these waves add up to give specular reflection and refraction, according to the Huygens-Fresnel principle.
In case of dielectric (glass), the electric field of the light acts on the electrons in the glass, the moving electrons generate a field and become a new radiator. The refraction light in the glass is the combined of the forward radiation of the electrons and the incident light and; the backward radiation is the one we see reflected from the surface of transparent materials, this radiation comes from everywhere in the glass, but it turns out that the total effect is equivalent to a reflection from the surface.
In metals, the electrons with no binding energy are called free electrons. The density number of the free electrons is very large. When these electrons oscillate with the incident light, the phase differences between the radiation field of these electrons and the incident field are , so the forward radiation will compensate the incident light at a skin depth, and backward radiation is just the reflected light.
Light–matter interaction in terms of photons is a topic of quantum electrodynamics, and is described in detail by Richard Feynman in his popular book QED: The Strange Theory of Light and Matter.
Diffuse reflection
General scattering mechanism which gives diffuse reflection by a solid surface
When light strikes the surface of a (non-metallic) material it bounces off in all directions due to multiple reflections by the microscopic irregularities insidethe material (e.g. the grain boundaries of a polycrystalline material, or the cell or fiber boundaries of an organic material) and by its surface, if it is rough. Thus, an ‘image’ is not formed. This is called diffuse reflection. The exact form of the reflection depends on the structure of the material. One common model for diffuse reflection is Lambertian reflectance, in which the light is reflected with equal luminance (in photometry) or radiance (in radiometry) in all directions, as defined by Lambert’s cosine law.
The light sent to our eyes by most of the objects we see is due to diffuse reflection from their surface, so that this is our primary mechanism of physical observation.

Here you go, a diffused LED panel like the one the vendor above is offering, but at a very reasonable price. I installed this setup in a single afternoon and have very little electrical skill, it is fantastic on my eyes, the color is stable and reaches all corners of my table. Just mate the wires in the power supply to the cord and crimp them (Match the colors accordingly, there is no guesswork)
2x4' Light: $90
Power cord: $4.95
Wire system to hang the lamp (if needed): $20

ya mine are more,
more money
higher specs
and a nice 5 yr manufacturers warranty, from a led manufacturing company
which you don't get when you buy one from those other guys

I'd be curious to see how the specs are different. Warranty is one thing but I wonder if there is an actual difference in quality or is it indistinguishable?
Blue Fin Billiards in Fresno, CA, previously known as The Break Room, has converted half of the tables from flourescent bulbs to Led lighting........the difference is amazing.......can't wait for the remainder of the pool hall to get done
Would anyone know if there's any recommended height for a LED panel? Just curious since the new LED lights hang much higher than the former flourescent fixtures since the profile is so thin versus the hanging wood box no longer used.

OP is asking about bulbs, not panels.
I use 3 LED bulbs in my fixture instead of the hot-ass incandescents I had before. Just pick the ones that are equivalent to 100W. It should say on the box.
I like a cool (daylight) color. The warm color range is too orange for me. I like mine bluish.
They are MUCH cooler, temp-wise. Like, almost-no-heat level of coolness.
Yes thank you. I was asking about just a direct bulb replacement. Thanks for all the info however.
not trying to knock this dudes hustle but if you want a light like this, go here: http://www.beeslighting.com/
I got a 2x4 50 watt, 5500 lumens, 4000k cool white LED panel for $129 delivered with chain suspension kit.

It would make things a lot easier to find a Lighting Engineer, let him come in, measure the lighting & make suggestions for great lighting (ergonomically - see lighting ergonomics). The engineer will also give you the correct nominal distance for the light to be hung over the table.
Lots of lighting companies use these kind of engineers in their sales team.

bulb color/typw
Assuming you already understand the science you posted above. What kelvin color temperature is ideal for a pool table? I prefer white-blue range 4K - 6K but perhaps what I like aesthetically isn't optimal to see details etc.? Appreciate your thoughts on this if you believe there is a superior option,
Using a 4 regular incandescent bulb light socket type over 9ft Diamond Proam. So option to use LED, Edison, or CFL fluorescent. Can adjust wattage to suit brightness desired so color/light type is real question?

Here are a couple of options up on Amazon:
https://www.amazon.com/dp/B07RG9WHXP/ref=cm_sw_em_r_mt_dp_U_0EMNEb4G71DD1
https://www.amazon.com/dp/B07SS2PXD8/ref=cm_sw_em_r_mt_dp_U_YAMNEbK1EWBR3
One is 5000K color (cool white) and the other is 2700K color (warm white). Note the one that seems overly expensive is for a package of two.
I am in the same position with my light. However, I have not tried either of these two options.
