I use the Fireflies NOV-MU with E21A 2000K every night. It is ultra high cri and emits the lowest blue wavelength I’ve ever measured. I also use the Clemence modded Skilhunt H04RC. Both are usb rechargeable and I leave them plugged in when running them at night.
You can have a little plant buddy to live inside too if you want. You can just set the (only) red light to be on for 3 (or 6) hours a day for your sunset. Maybe turn on 1 hour before your other lights turn off.
There are lots of versions of these in many shapes and form factors. For ease, this is a screw in bulb.
I haven’t used this one, but I imagine it will last longer just using red at maybe 14-22 watts of power.
Edit: The linked light has clones sold under different names. They have a typo. It has 28 red (620/660nm), 18 blue, 18 warm white (~1.8-2K) diodes.
This meets your requirements (& of NIH study) if you want no blue or green at sunset.
The light I got was ten years ago and the Ott Co. offered CRI rating at the time. Current company bought him out and right, I don’t see CRI on their pages. Probably because everything they make seeks to be like daylight. An impossible task but everyone tries. Oddly, or interestingly, the quilting world uses Ottlites for judging fabric color. I use one to check color balance on photo prints, and it’s the best I’ve found so far. The waveform bulb you ordered looks good. Think I’ll try one. Thanks for the idea. I’ve had trouble with specialty bulbs holding up, but maybe this one will. The LED bulb companies claim theirs will last five years or ten years, but they never do (for me) and I rarely save receipts that long, and they know it.
first impressions… seems nice, glad to have it as an option
I removed an incandescent that is rated at 29 watts, on my meter it makes 8 lumens, and gets too hot to touch
I installed the waveform light rated at 10 watts, it makes 70 lumens on my meter and it is not hot to touch
so, the LED bulb uses 1/3 the power, and makes 9x the lumens… and so far the color rendering seems good, and the tint does not seem green… I think I like it…
You can buy them from China directly now. No blue spike and appears to use the same “sunlike” chip. Almost identical to incandescent. I wish they come in retrofit or BR30 format though…
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) https://item.taobao.com/item.htm?id=654264933998
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.
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?
