A lot people never liked daylight bulbs back in the 50s and 60s, but I did, maybe that is why I don't see all that good today.

Why would that make you not see good? This lamp is likely from the 90s though not the 50s or 60s I actually find daylight vintage tubes are more common than warm white or white tubes but it seems cool white has always been the "industry standard". All the T8s i see now are typicall 3500K or 4100K though. Once in a while i'll see a small installation with cooler T8s. Walmart uses cooler kelvin rating T8s in their produce sections, at least at one store near me.

I just love the simplicity of this etch! the Pre-mid-90s fluorescent lamps had nice and simple etches. Now fluorescent lamp etches have all these crazy codes and crap on them that is unnecessary but the stupid government regulations...

I don't think Larry was specifically talking about the tube above

I know that. I asked why daylight tubes would affect your vision.

I don't know, it was just something that was thought back in the 1950s by some people. I don't think it was just daylight bulbs, but fluorescent lights in general. Just like sitting too close to the TV type of thing. In the 1950s this kind of lighting was new to many people out on the farm and in rural areas. New fangled stuff.

Ahh I see what you mean. I wonder if the TV thing is legite. I never thought it was but nowadays more and more people wear glasses and lighted electronic devices (speaking of TVs, computers, phones, tablets, etc) are much more common so I really think the two are connected, though it could simply be the case of if you look at close-by objects for prolonged amounts of time, your eyes will become "fixed" on them and you'll become nearsighted. I need glasses for distance (I'm nearsighted) and my vision really went downhill after I started going online more.

It's like how people claim CFLs give them headaches. I suppose the fact that CFLs emmit a high frequency pitch that is undetectable to the human ear but is enough to trigger headaches could be plausable but the fact that the glow from the CFL itself gives headeaches is absurd. CFLs and linear fluorescents are the same thing, just ones is coiled up and run off a half-@$$ "ballast" and the other is either driven by a better quality (but still crap) electronic ballast or a good old magnetic brick.

I say long-live the good old stuff! Incandescent lamps, HID, and magnetic linear fluorescents never let us down in the past so why abandon them for something new that is destined to fail?

I think the lighting ban is mostly a power grab by someone as most people switched over to CFL five years ago. I don't think 100 and 60 watt bulbs were a red hot selling item, until the ban anyway. May be it is just me, but LED lighting gives me eye strain after a while. LEDs are ok for some things, but for general lighting, not for me in my house thank you not until they are as good as incandescent or fluorescent, which I think is going to be a while. When I was a kid, my father was a incandescent guy all the way. It was incandescent lighting or nothing. He did not like my fluorescent lights at all, even though they were free all you wanted back then if you went dumpster diving. I put some up in the basement and the next day they all came back down. I had a uncle in eastern Kansas that owned a farm and was about 20 miles from any power line. He used kerosene lamps, wood stoves and flashlights up until 1975. When I go there in the summer to stay awhile, it was just normal to go to bed early and get up before sun rise. They did not mind as that was the way they always did it.

What state do you live in? Up here in the northeast incandescents are still the big thing in residential homes. I don't know too many 100W incandescent people but 60W incandescents are found in just about any house you go into here. I know some people that have a few CFLs they bought to try them out and even one or two LEDs but the majority of their lights are incandescents. I just hate the foggy tinge given off by the "soft white" CFL lights.

I have LEDs in my room that i bought back in 2012 I think. There's three in my ceiling fan light. They don't illuminate the ceiling (they're more like floodlights with an opal globe tacked on) but they give off a nice color and are pretty bright. We have some CFLs too. My brother's bedroom has two CFLs and one 40W incandescent (one CFL failed so se screwed in the first lamp we found lol; a philips Duramax from God-knows-when), and my parents room used to have two 13W CFLs but it was too dim so I think I installed something different... I don't know... The kitchen has a 4X lamp fixture with CFLs and the dining room does too. The bathrooms and the basement lights in the finished portion of the basement have 53W halogen lamps for more light than a 60W lamp and less energy than a 60W lamp.

I like the halogens for that reason plus since the color of the lamp is whiter. I Find the GE halogens are crap though. For some reason they dim out and then extinguish. I installed one GE halogen at my grandparents' house after i changed the fixture over their sink out and I thought the lamp looked dimmer than normal and I went by it an hour later and it was giving off the light of a 7W nightlight lamp even though it was a 100W equivalent lamp. So i replaced it with a Sylvania halogen. Maybe I'm biased for whatever reason, but I just love Sylvania lamps. If i see Sylvania lamps in a store when I need lamps, I'll choose Sylvania over GE or Philips (or any brand for that matter, unless I'm tight on cash and need to settle for a no-namer).

And in my basement, I had group-relamped three out of the four dome lights in my basement with 53W soft white GE halogens and I swear one is dimmer than the other. They're all in identical fixtures with identical lamps, installed at the same time and on the same switch. By looking at the two lamps themselves you can't tell that one's dimmed out but looking at the room as a whole, one half is darker than the other and it has to be the lamp since i just noticed it recently. I'll see if anyone else in the family notices. Those fixtures are a PITA to open with all the little nuts and bolts and washers and stuff so unless it goes out completely or becomes useless i'll leave it in. It's probably giving off the light of a 40W incandescent though it's rated to replace 75W incandescents.

My guess is the GE halogens have bad capsule seals just like how the GE MV lamps have bad arc tube seals. I don't have any lamps on hand but I'll probably buy 53W Sylvania halogen lamps if i need to get them again.


Wow! He didn't have electricity? was their a lot of soot in his house from the kerosene lamps and wood-burning stove? I'm the boy scouts but I've never seen a kerosene lamp in action before. In warmer weather we're in tents but whenever we're in a cabin it always has electricity (at least lights, smoke detectors, and an outlet or two; a gas stove if we're lucky and some cabins even have running water or even a toilet but if not we have our own portable stoves and we bring water jugs to fill up at a pump station, which would be provided if there was no water in the cabin)

I've heard after so many minutes (I think like 20) of computer use you should look off into the distance for like 20 or 30 seconds to let your eyes refocus. I did as I was typing this.
As for CFLs, the 2700K ones to me look nothing like incandescents (I can tell the difference) but it's good enough for me...although I like 5000K CFLs better and have both color types in my house, though I only plan to buy 5000K or 6500K ones in the future. Same for linear fluorescents- 5000K or 6500K if I ever have to buy any (I'm already set for life on 4 footers for just my house).
I know people who live without electricity. I have 27/4 power although it's off-grid but I have a woodstove for heat and it's not THAT sooty but it's a very "dry" heat; not much humidity in my house!

Yeah the 3000K CFLs seem to be much better though. Eh for linear fluorescents i prefer 3500K/white the best. I like the 5000K lamps but they flicker a lot. Daylight is good in a room that doesn't see sunlight but when the sun's out it's way too blue for me. I like cool white but it can be boring... white is still a neutral color but it adds that warmer household feel too it without getting drab or pink like /WW. 5000K has a vibrant work-zone feel to it but the flickering lol. And it sort of gives more of an industrial look instead of a more homey look.

ahh what we do on camping trips is put a pan of water on top of the heater if it's a wood burning heater. it keeps a little but of humidity in the room so you don't wake up with a sore throat or get a nose bleed (since some people like my brother get nose bleeds easily when it's dry out)
