Yeah, I did a quick Google and can't find it. I'll have a look in the stores some time.

I wonder if the tinting of LEDs to warm is difficult, inefficient, or creates additional heat that affects the emitted.

Nice find, thanks :) That's a decent brand, not really known for lighting. They're a little less efficient than the big brands, but that may be because of the color temp.

It's 13W but stated brightness is only 1055 lumens, which is the same as the 10.5W Philips one I linked. And the Philips one has the bonus of being dimmable.

Lack of demand probably. People that want things dim and orange generally don't want things bright.

Same reason that its damn hard to get bright e14 based lamps - those are normally used in quantity in chandeliers where people are accustomed to dimmer oranger lights so that is what they make there. Bright workspace lighting is seldom warm colours so people go for the cooler ones now that they have a choice.

Interesting thoughts @richms.

Bright light, especially white/blue light, inhibits melatonin production, meaning you won't get to sleep so well. This includes phones, tablets, TV, and lights.

We only really use overhead lights when we're doing tasks; when we're watching TV or going towards bed we use lower powered lamps. So the color temp of the lights probably isn't critical, because we're actively doing things.

Given that, perhaps I'll just use higher powered 3000K lights, Philips or Panasonic. I do quite like the light quality from Panasonic, it seems nicer than CFL.

That seems to be a trend among people saying that. I suspect a lot of it is just trying to blame the blue light on other changes in lifestyles that have happened. with screen time and devices etc.

If blue light really stopped you falling asleep then I would have my place covered in 8000k or higher lights so I didn't doze off waiting for grand theft auto to load.

Source: Harvard Article. Alternately google "blue light melatonin suppression". I don't think you can call it a trend, I'd call it a fact that it reduces melatonic production.

Melatonin isn't the only thing that allows or prevents sleep, it's just one factor - temperature, situation, all kinds of things. So blue light won't prevent sleep, it just makes it more difficult to get to sleep.

Not sure if this is 2700k but might be worth checking out: https://www.cheapies.nz/node/11314

Daylight on the pack, and its a pretty lousy brand. I got some of their filament ones figuring at the price they must be way better than the aliexpress ones I got, and they ended up being way worse. The philips filament ones are very warm and may suit the OP, and no flicker either.

2700k leds are very orange, far more so than just a normal incandesent light. 3000k warm white tends to produce a better light. If you go to mitre 10 they have a range. Orbit brand do them.

2700k is about what a long life 1000 hour incandesent light puts out. 3000k is what a proper halogen will do. The big benifit of halogen other than long life and efficiency and small light source was its better colour temperature, so not sure why the desire to go backwards.

Just been in Mitre10 Mega Albany for something else so passed by the lighting section and they had some warm 13W GE LED Dimmable. 2700k and 1060 lumens.

Can't find them on the Mitre 10 website though and the GE site isn't very helpful either.

Pretty sure they were A19.

It comes down to preference and what the intended use of the lighting is. I don't think you can say that the 3000K that halogen puts out is a "better" colour temperature, or that wanting 2700K LEDs is going backwards.

For a living room I personally think 2700K is about right, and when dimmed I tend to prefer even warmer than that.

In theory they should be. But not sure how well colour matched the models being sold in NZ are. I have compared a 2700k LED E27 I have got in a table lamp, vs a normal 60W incandescent, and the incandescent is definitely a whiter , less orange light. The 3000k is a better match I have found, although the 3000k is a bit of a whiter light. But lighting professionals I have spoken to have said they would only use 3000k in houses. Many stores sell 4000k in bathrooms, which they say produces a better light colour for putting on makeup etc, but I think it is too much of a cold light.
