T8 Lights loosing their brightness?

[Industrial Toys]

I wonder if T8s still have heating filaments. I am thinking not.

....I only had people work on installing them when they had no paying work to do......

That reminds me of my last job. Sometime during the 1st year I was there, they gave me a SKID of ballasts, an old rickety 16' metal step ladder, a case of wire nuts, and a pair of wire stripper/cutters and told me to change every ballast (old PCB ballasts) in the building during slack times, while they were live! I grew to hate that ladder. :laughing:

We had the wooden ones that weighed a ton! And yes, nothing ever got turned off.

My late father-in-law used to do that all the time. I've done it a couple times on 120v. Most of ours are 277v...

Wooden bulbs? They must have been before incandescent bulbs. Probably direct wired with knob and tube.

Actually, I'm saddened, one of two 500 or 1000 watt mogel base bulbs in my garage just burned out. WHAT NOW?

I was reffering to some awful old wooden 14 or 16 foot step ladders, that I could barely lift as a skinny kid. They also swayed side to side. Then you had to hoist them back on the roof of the van and tie them down with wire! lol I'm sorry, we never lost any!

Trailer at work today now has LEDs in the ballast. Yes it was bright. Wired without ballasts. I was told if you use the ballast probably going to last forever,but more expensive to run.

Brought up how if they last forever, they are going to get dirty. Guy said we will take them down and clean. Which I then said, how is that different than changing a lamp?

If the situation comes up I will go with LED. But I am not taking down functional lights.

How can you expect to ride on the bandwagon, then?

It's not just longevity, it's Lumens per Watt.

But if you don't care, it don't matter.
