What is the best solution for circadian-friendly artificial light?

Neither can most. Taobao is basically a chinese only webstore.

Just use Chrome’s translate. You can order with their built in forwarder. Search the web, there are tutorials. Or use an agent.

Good idea!

I've been avoiding Taobao because it's not in English, but I think I'll just using Chrome's translate.

I hear that things are usually cheaper on Taobao than on AliExpress.

It depends, for small light stuff AliExpress is cheaper. If you buy heavier stuff, or aggregate multiple order, and forward it once, then Taobao.

Btw, this is the newest version with an even better spectrum, notice the efficiency loss as a result. (You can kind of estimate the spectrum just by looking at the lumen efficiency)

Forgot to mention, for night light I went back to halogen/incandescent light since they are literally perfect lights…

In addition to the blue light much dangerous for night sleep It’s looking direct the Led die.
This happens when there isn’t adequate diffusion such as a piece of white plastic.
Like the Led Corn bulbs,the orrible greenish street lamps or the ice cold car lights pointed on face.
Another important rule, avoid watch phone or others white display light in evening
The conventional PC Leds with the same amount blue light of incandescent are <2000k
However I liked dimming incandescent on my bedroom,easy and cheap.

Hi,

About a month ago I tried to order the bulbs at sunlikelamp.com, but he does not accept PayPal anymore. I wonder if I could get bulbs made with sunlike LEDs via other sellers, does anyone know?

If you want the exact same chip, you can buy it from https://item.taobao.com/item.htm?id=585513116587

But an improved spectrum is now available at 商品详情

thaks for the link
I failed to translate it with google in Firefox, but it works in Chrome

If you use chrome, just right click and select translate

thank you… that partly works (about half the text is still chinese, but some of it is English)

unfortunately:
Working voltage: 220V

here in USA I need 110V

if there is a 110V option, Im interested… still looking

It’s universal voltage 110 - 220v, I have it here in the USA and it works :slight_smile:

yay! thank you :slight_smile:
ran into another issue
the link to put the light in my cart does not work… oh well…

I am getting ready to order the 2700k from Waveform.

I tried the 3000K but returned it due to green tint… Customer service was outstanding, they even provided a return shipping label.

Yeah, I tried some other 98 CRI leds and none of them look natural until I came across this one.

With that said, just use incandescent? I only bought these to avoid overheating my recessed lighting.

same, some of my fixtures overheat with Incan

so Im on a quest to find good LED options

here is one I like so far: (I bought the 3000k)

the tint is great, colors look great… it is a bit brighter than I need for some of my relaxing applications

Waveform LED got quite a big blue spike in the spectrum. I was considering them but cross them out because of that.

thanks for sharing info

> big blue spike

where is that data, Im new to sorting LED options and dont see a spectrum on their site (yet)

They don’t publish the spectrum when it’s not as good, but here’s one https://www.waveformlighting.com/photometrics/TR_4005.30.pdf see it spiked to 40% vs the taobao one which is at 15%.

Oh yeah, if you don’t care about the blue spike you can get the high CRI bulb super cheap here Amazon.com

It’s 98 CRI BR30 and dimmable too.

thanks for the blue spike info on the 3000k Waveform (is that the filament bulb?)

fwiw, darksucks sells a filament bulb (that looks a lot like the 2700k Waveform)
the blue spike is lower than 40, but more than 30:

it is a 600 lumen equivalent

the photo grade lamp I got from them is 800 lumen…

> you can get the high CRI bulb super cheap here

excellent bulb!
850 Lumens is more than Im seeking…

Im looking for 400 lumens (hence my interest in the Waveform 2700k)

I think I see a dimmer in my future :wink:

much appreciate all the info… Ive been confused about LED home lighting options for a long time…

Be careful, filament LED are known to flicker. I’m not sure I would trust that site.
Eg: Waveform’s filament flicker at almost 20% https://www.waveformlighting.com/photometrics/TR_4002.27.pdf

The more research I do, the more I realize incandescent/halogens are the perfect bulbs…
