Did you give your old light bulbs to someone who will use them till they die?

Ed, glad you found those 6000K tubes. I didn't see them.
Please educate me. What's the difference in K value and why do you like the 6000K ones?

I have been studying changing from fluorescent lights to LEDs . I have found three ways.
1. New fixtures that are LEDs.
2. Buy LED replacement tubes that use existing fixture ballast.
3. Buy Led tubes that use the existing fixtures tombstones but does away with the ballast.

I have found these 3 options in most temperature ranges. Cost are similar for the tubes but new fixtures add to cost.

I like the idea of doing away with the ballast because I have few fixtures that have iffy ballast.

My concern is do I want fluorescent type fixtures or would I be better served going to LED flood type fixtures. Back in the day fluorescent type fixtures made sense but if I'm going to convert to LEDs spots/floods may be a better method.

Any thoughts ideas experience?

If the number is say 2700K then the light is called warm or more red in nature. As the number goes it it becomes more white, cool, and sometimes even blue but it more like sunlight.

It depends on what you want, I like it at least 5000K or even 6000K and I have seen bulbs rated at 6500K. This perhaps is not the best light when trying to determine actually color, sun light is best of that unless you know the item is going to always be in a home and where a different color balance might exist.

Some people who are very into make-up have mirrors with adjustable color so they can see how they might look at a party or how they will look in church etc. I know some wood workers who have gotten those to use for looking at finishes..... no not me, we don't have one of those in our home.

Lighting color spectrum is very important in the finishing process I found out after pull hair out!!!! I was trying to match a finish to a prefinished vanity, my shop had all CF in them on the white/blue side more brightness, and some 48" tube Florescent on the warm side, well at one bench with the warm tones, made up a sample piece using dye and oil based finish, hit it perfect with some adjustment to the dye.
Over to the finish bench and did the project, way off, WTF!!!! A commission project to boot.It was the same when I figured out I was under cooler/blue light spectrum at the finish bench after I took it to the warm, more natural light over where I did the sample piece at the work bench. Then changed all to the same spectrum. Lesson learned!!

I'd be interested in the shop LED stories people have.

Not so many years ago I updated my shop from the T12 old style fixtures to the T8. That produced results that I have been pretty happy with. Not only much brighter then the aging T12 but a lot more efficient as well. I liked the fact that I could get a much whiter light as well. The T8's are all electronic ballast so the flickering is gone, they come on much faster and have no problem with the garage/shop being cold(but still above freezing).

The fixtures I put in my garage have electronic ballasts, but are compatible with both the T12 and the T8 lamps. When I put in T8 in one fixture and T12 in one beside it, the T12 lamps put out significantly more light than the T8. One would expect that as they use more power.

I switched pretty much all the lights in my house to LED. I find that only the daylight color LEDs are worth putting in. The soft white are barely better than the old incandescent lights. Fluorescent lamps are the same. Only the daylight color really put out decent light. The lower color temps are poor light.

Isn't lumens the measure of the amount of light produced.

If you have two lights one 2000k and one at 6000k but both producing the same number of lumens won't they be the same brightness? I understand one's eye might preceive one brighter than the other but isn't the fact they are the same lumens saying they are the same brightness?

Does a spot/flood light produce more light to specific area over a tube light?

Yes Lumens is the amount of light produced, that is why I did NOT go to LED Florescent tubes replacement a few ago, Lumens was about a third less. I dont know now at moms. BUT color spectrum is different then Lumens

as I posted earlier blue/white light at the same Lumens looks brighter then warm/sun light at the same lumens, but found out under Finish it totally changes the yellow tone to it.
