My stoopidvisor bought a large quantity of the first gen LEDs for the rock farm. I think he was more interested in the sales rep than he was in the light bulbs, she was very attractive :D . The asphalt plant I operated has a 600' long tunnel to provide 5 different materials for the different kinds of black top. It's dark in there 24/7. The tunnel was made with railroad tank cars welded end to end :wtf:. It makes sense if ya think about it :realcrazy:. Those LEDs projected one little bright spot on the opposite side of the tunnel and did nothing to light the work area and only lasted 90 days maybe. Being inspected by 2 OSHAs the lighting had to be protected just like a mine, glass enclosure with a protective metal cage over that. Those cages were 9"? deep so most anyting would fit in there. I found that the screw in flourescents had the longest life span some as long as 5 years. What can I say? When I was the oiler/fireman I had some time on my hands and soapstone in my pocket. When I replaced a bulb I put the date on the tunnel wall :lol:.

The CFL's did last a long time. They would still be around if not for the bad stuff in them. Ya, the early LED's were better at spot light than flood. COB technology really helped there. I have a few places these might be a good fit. I don't know how good they are though.

We are required to give students some homework on doing a case study or an event, it is part of the curriculum content. It will be a very interesting training day on Monday as a result of the incident in Virginia and the six year old. I have a feeling our students may pay very close attention.

I haven't seen any details come out yet.
Almost sent this to you yesterday. This JROTC 'kid' is a hero.

This 17-year-old Philly student saved a gunshot victim. He’s being honored by the U.S. Army as a hero.

The victim was fading in and out. “He said, ‘Bailey-Taylor, please don’t let me die.’ That message will always stay with me.”

Which also also served as reminder my last first aid and CPR training was way too long ago...

Ah, I see my radiator is out for delivery. I might wait for 40° and sunny on Monday to install it. Sounds like more fun than teens an cloudy today.

Old eyes...

I use the high lumen ones in the bathrooms... mid-range in the multiple bulb fixtures and the old school looking Edison bulbs in the Den. Surprising variety out there now. I scored a bunch off the clearance shelf at Lowes a while back and they're decent for general use.

That's basically what I do. High lumens where needed, lower lumens elsewhere.

I got a bunch of LED at HD -their Ecosmart brand. The soft white is 2700k and looks too yellow. Bright white is 3000k and still somewhat yellow but works for most. Daylight jumps to 5000k and starts looking blue. I thought they used to have 4100k - which to me is the best actual white light that I want for 'office' area... Gonna check other brands.

At one point a few years ago I looked into replacing standard 40 watt 4' flourexcent tubes with LEDs. The ones at HD actually had less lumens than the T12s...
So far no LEDs here except in the cordless stuff (flash lights, and such).
I like them for for concentrated light but don't like how directional they are.

When LED's first came out they were total crap IMHO. I turned down many sales people pushing them for use in the freezers. Some would have you believe they would never go out... still don't live up to the lifespan ratings. Did a few tests and the lift operators hated them. Just a bright spot of glare and no light to see the product on shelf. Another lie was 'they don't give off heat'. The face was cool, but some of the fixtures I looked at had a massive heat sink on the back. The ballasts would fail and the entire fixture is scrap. They are improved since then, but still not up to the original expectations.

Yes... the early LEDs were horrible.

They do seem to be getting a better handle on the effectiveness of the LEDs. I had a 500W halogen that was put in the recycle bin by our electrician, an outdoor area fixture, glass cover, swivel mount, the whole bit. It still worked so I modified it to be used as a drop light. One of it's main functions was keeping one of the air over electric solenoids on the plant from freezing on those cold winter nights we get :lol:

No rush. Sit back and wait 'til you get to work under someone elses and then decide.
Remember the big push to compact flourescents?

I think the T8s are generally pretty good for area lighting if not placed too high.

LEDs will get probably continue to get better, or something else will come along, especially for area lighting.

I've seen those... not sure.

I went with the LED shop lights from H.F. you can daisy chain up to 4. 5000 Lumen each. The garage is super bright

LED drop light can be a bit annoying as directional as it is.

nothing much just at work early today to set up my bay. we just expanded into a new shop that has 2 more bays. mine is 3000+ square. ft. and the other is roughly the same. it's very empty so I'm putting up shelves and trying to fill it up a little.

Like some of the claims when audio CD's came out. Industructible they said. Could throw them like frisbees.
I was intrigued until not once but twice in one afternoon the DJ put on a CD and there was radio silence. Uh oh!
That technology got better too. Too bad they never dropped the prices on new ones even though they were cheaper to make than records.

The screw ins are actually very good for light output now. ‘Bright white’ looks good to me in most areas. I just want a whiter light for office. None of them seem to play well with the dummer in bathroom which reviews said should be good for LED. Even tried swapping in one incandescent. Supposed to stabalize the voltage. Still flickers.

Is your light part of the exhaust fan or heater? Mine is and the only bulbs that will last are trouble light bulbs. (because of the vibration)
