I have a nice "40-60-100" LED that's 2,700K and a 25-watt filament lamp in my desk lamp (some of the few filament bulbs you can still buy are 7½-, 15- & 25-watt lamps, due to their low voltage) and I honestly cannot tell the difference between them, there are no lines and there is the same warmness to the light, maybe the 25-watt is 2,500K-ish more, but those are both still "warm light" and close to each other (I detest cold light too, I have Seasonal Depression enough already and my phone, tablet and laptop all have a blue-light filter on them) – the only reason I hold onto the 25-watt one is because 25-watt LEDs are hard to find and these aren't…as the 3,000K CFLs and remaining filament lamps (some rarely used lights) burn out, we throw them out or recycle them, depending which kind they are – the Target here has a place to put them, and replace them with 2,700K LEDs…I can tell you that the 3-way LEDs bases are HEAVY, they must have some hefty circuits inside.

Fluorescent tubes give me migraine attacks complete with aura, and so do CRT monitors. Being in a grocery store for more than a couple of minutes would trigger it, so it was a great relief for me when they stopped using them. Concert show strobes and new LEDs do not trigger it.

I came here 4 years late, only because I'm just going through your videos that sound exciting to me. (New subscriber) At the time of this video, LED bulbs were fairly new, and color-changing ones were kinda expensive. Now I have a smart LED color-changing bulb that I bought for 5 bucks. A year later, still runs like a champ.

Also, I want to congratulate you for making over a million subscribers. At the time of this footage, you only had 35,000. So congrats again.

Now that I wrote this, I realize that you or your team (if you have one) probably won't even read this. Lol.

I remember the cfl era. They lasted for a short period. I always found them dizzying and felt I was catching a fever but never understood why.

I love watching old videos of popular channels when the maker talks about how many subscribers he has. It's awesome to look now, 4 years later and a entire 1 MEEELION subscribers more … Love the channel now in the future…

If you ever do a follow-up, I've heard that the harsh blue light of CFLs can cause issues for people with glaucoma, including headaches!

What do you mean not directly visible? For me it is sometimes pretty obviously directly visible, especially when looking with the corner of my eye.

I just want an LED with color rendering on par with incandescent but with adjustable color temperature like how my miniture filming lights have two sets of LEDs with one cool and one warm and the ability to adjust the amount between them.

Leds are too damn bright. I cant even see when driving if some turd has led lights. But seems im using cfls in my house (those spiral bulbs). Maybe thats why were getting headaches.. We used to use the old fashioned bulbs and were fine, then they quit selling those, we ran out of extras, and were forced to use the cfl (thanks again obama /sarcasm). I do notice we get headaches and migraines more. We attributed it to stress or age but.. Maybe its the lighting…

LEDS are like marriages. They can last very long and are intended to do so but most don't

Way back in 1976 I started a job as an artist for a custom silkscreening shop. After a few months I thought my eyes were going bad. I had terrible eyestrain, and even when I wasn't at work my eyes could hardly focus enough to read. Then someone suggested the twin-tube fluorescent lights I worked under might be the problem. So I removed the tubes and just used my incandescent desk lamp. Very soon my vision returned to normal. 

Later we replaced the old fluorescent fixtures with new ones, and I never had any trouble with them. To this day I don't know if the old fixtures had a defect that caused them to flicker at an abnormal rate, or the newer ones just didn't flicker as much.

Nope and also CRT monitors also did not cause eyestrain unless you had it calibrfated wrong.

Wait, is that some filament in your corner around 10:00? If so, why?

I can see the flicker of some LEDs. (Most honestly) I wish there was more information on them when buying them.

CFLS flicker at 60HZ/second. Cheap Chnese LEDs flicker at twice that. Headaches are the result regardless.

I was impressed on the improvements made to CFLs over a decade's time, as I recall 20 years ago when they were first widely available and affordable, they didn't throw out the brightness of an incandescent bulb; although the CFLs of 20 years ago were marketed as equivalents to incandescent brightness.
Going back 20 years there was a demonstration display of CFLs to incandescent bulbs of equivalent brightness, where flipping a switch would light up the incandescent bulb; flipping another switch would light up the CFL next to the incandescent. To this day I still recall being able to closeup stare straight into the lit CFL with eyes wide-open; where the equivalent 60 watt incandescent had a brightness several levels higher than the CFL, almost blindingly bright, where I had to squint my eyes to view it.
But, years later the brightness of the CFLs improved immensely.
