The General Light Bulb Discussion

[Ridox2JZGTE]

I replaced my living room old CFL with LED a few months ago, even at very low power rating, it's too bright for my liking, and I had to turn it off when watching movies at night, it's killing the dark details of my tv.

Use dimmable LED and install a dimmer switch.

That didn't come up in my search, apologies.

LEDs with the daylight output all day long. I can't stand the dingy yellow light most bulbs put out.

Nearly every light in my house is a CFL, that I know of. Aside from the backyard motion light I replaced in the spring which is LED.

Same, I hate warm white.
Even in my car, nearly everything is white LED.
Saving up for some good LED headlights.
If I can find true yellow ones in a HB4 I will install them into my fog lights.

I like LED light bulbs. They tend to brighten my day.

I like LEDs, but I am extremely fussy about color temperature and, more importantly, CRI or Color Rendering Index. CRI is somewhat flawed and is not a perfect predictor of light quality, but it helps as a datapoint. Most LEDs, even in the supposed warm color temperatures, have a blue cast I don't like. And they are way too source-dependent - consistency is poor and a lot of them bring out really weird overtones. I have LED undercabinet lights in my kitchen, and they look fine in general... but as soon as you put meat under them, it turns a nasty purple. I have to make sure the overhead halogens are on to get a good idea of the doneness.

There are really really nice LED replacement lamps available that put out really good, high quality light, but they are still on the expensive side. The technology continues to improve, but the consistency isn't quite there yet.

I don't like fluorescent lighting of any kind. Even the best has terrible color rendition and temperature, and they flicker at 60Hz (or whatever your local AC electrical standard is). That drives me nuts.

I vastly prefer, subjectively and aesthetically, the cozy yellow/white from a halogen. They aren't as yellow as a traditional incandescent and are about 10% more efficient. They're still not efficient enough for this day and age, though. I use them wherever color rendition is most important.

I recently bought a LED bulb. It is almost 200% more expensive that classic bulb of the same power, so I hope it will last for a while. On the box it says 3-year warranty, but contacting the manufacturer directly could be quite inconvenient and probably not worth the trouble and patience.

The bulb doesn't warm up at all and it emits blue light. Good for lighting up the room, but it takes time for eyes to get used to it.

So far it seems it is best to keep LED bulbs in places where lighting is often on and where reading or writing is not required.

The tube light in my kitchen is only used when I am doing some elaborate cooking, which is not that often, or if i'm using the rubber mat I have on the kitchen floor as a workbench for something technical which is also rare.

Well I decided to replace the 36w T8 fluorescent tube light with an 18w/1800lm/6000k LED alternative, it's an amazing difference, the clean brightness of it plus the instant on it is a much more pleasant experience than the horrid warm orange-ish/yellowy light of the fluo that would flicker and buzz for 10-20 seconds at start up and take a further 20 to reach full brightness.



Highly recommended.

A long time ago I remember (I think) reading that blue LED lights were the cheapest to produce, hence their use in most small 'on' lights. Whether that is still true to these days I don't know but I can't imagine that making other colour LEDs has become cheaper just because it's later in time but it does make me wonder why manufacturers didn't just put a clear coloured casing over a blue LED if that was/ is the case.

 

[Matej]

Probably unnecessary question, but just in case - does the CFL bulb radiate when the power is turned off?

LED
no question
they work great,
and don't break when you drop them
