Flourescent light problems

[farmersamm]

It's a a few dollars more for the led retro kit I posted. By the time you buy 4 tombstones, a ballast, and two tubes.

Good tubes are becoming a problem. Ballast are also a problem. They last 3 or 4 years, not 30. The LEDs also put out twice the light.

The only bulbs with equivalent lumens to the t-8's I'm running now.

My current fluorescent tubes are around 2500 lumens..................32 watts. So, I guess saving 8 watts per bulb would be ok. But I'm not sure how the LED's handle heat. The ceiling of my container gets HOT.

I'm using 250 watts at present, and plan to add one more fixture, bringing it up to 320 watts. So.........at 24 watts, I'm only saving 80 watts on 10 tubes.

I'd still have to get rid of some of the crappy flat spring style tombstones I have, and replace them with the newer/better versions.

I know that I can't use the standard 1800 lumen things the big box stores sell..........that's a step backwards. But.....I'm not too sure that the 3500 lumen tubes might not be over bright.

Navy uses them in some harsh environments.

The ballast bypass kits that I referenced include tombstones.

The engineers at work would not allow the old fluorescent light fixtures in the office to be replaced. Because it was a " nuclear site " and may affect nuclear safety . was going to require an engineering review .
So I ordered these substitubes and we all installed hundreds of them . The engineer was frantic for a while, even though the old ballasts, old fixtures nd old sockets remained in service . Most of the site is using them now .

Check out the prices for LEDs at RK
LEDs work in the winter. Last longer too. Uses less electricity

Good price, but they show out of stock, when I looked. Could that have been a clearance price? No RKs in Maine, how much you suppose shipping to the Bangor, Maine area would add?

I have had good luck with the 4', 5500 lumen linkable hanging lights from HF. Usually 17.99 when on sale (sometimes less).

High lumen lights seem to be a problem with low ceilings.I got some from a friend that had them on his eight foot ceiling.He was always squinting and angling his head because of the glare.I used them on a 14 foot ceiling and they are OK there.When you walked in his shop you kind of had to furrow your brow and look down.You could NOT walk into his shop and look straight ahead.

Good point. Setting light value and glare/reflectivity is part of any application. My 60 years in technology labs has experienced the full gamut of too little too much too far too close. Too much is easier to fix by rewiring for two or three levels of illumination. Jim

I have a cheap RK high lumen 4 ft light in the middle of my 24x24 attached garage, 10 ft ceilings. Plenty of light. My garage is finished, white drywall on the walls and ceiling. I almost need sunglasses.

At my age, I can't get enough light. It's better with the cataracts fixed, but I still really like the multi 2100 lumen fluorescents hanging as low as they do in the shipping container. I believe it has to do with the rods/cones in our eyes as we age.......or something like that???

There seems to be little attention to temperature but in many cases it can be important. Woodworking shop being one and certainly anywhere painting is done.. Front overhang of shop is used for cookouts and gatherings so after having leds hung in 2021 I had both fixtures in overhand and first inside shop put on separate switch and warmer tubes installed. Much more relaxing.
