Two interesting products:
Battery and AC powered RGBWW high CRI smart BULB, flicker free dimming. Yes, all that, supposedly:

Great comparison SKV89, thanks.
I have to say, I use my C-800 way more than I ever expected. The plan was to test everything I owned, then re-sell it. But I’ve had it over a year, and I still need new readings and comparisons every few weeks. One of my new hobbies is growing Oyster mushrooms in a tote, and their light exposure affects their color, texture, and vitaminD content. So I am using the spectrometer to take readings from the best locations and simulate it with my selection of LED strip. It’s just awesome.
Great feedback! For the TM30, is that something you can derive from dumping the spectral data onto your computer?
They can probably even add it to the software they seem to be able to customize it
It’s probably crippled on purpose. They support TM30 on some of their other meters.
This site has a lot of tests.

What are the options for 1500 lumen and above daylight bulbs?
Put up a new light fixture in my office and tested some new bulbs. Ceilings are 14’ (don’t ask, I have no idea why) and it had a frosted flush mount light fixture with 2 garbage 2700K bulbs in it. Needless to say I needed WAY more light and something a little more unique for my uniquely tall office.
10 bulb Sputnik light @ 100% brightness (it’s basically outdoor level brightness on max ~800x10 diffused lumens?)
EcoSmart 60-Watt Equivalent A19 Dimmable SMART LED Light Bulb Tunable White (2-Pack) ($4.99 per bulb, these are clearance priced I think)
Sorry in advance for international people but this is a pretty good value for people with a ZigBee hub. It’s a house brand of Home Depot (US home improvement chain). It’s tunable from “2700K” to “6500K”
Here are some measurements with the light at 30% brightness:
2700,3000,4000
4500,6500
Considering I prefer ~3000K for indoor lights I am pleased.
Sunlike 15-16D
Woah, that absolutely blows away my Hue Ambient, which are about Ra 83. Thanks for the tip, just ordered 8 to try. Love the Duv at 3000k, as that’s my go-to interior light.
I see that Yuji released a CRI95 zoomie bulb:

I wonder if there’s a chance of a res-mod or another power upgrade….
Sunlike is good and better CCT but longer wait and higher price.
They said they “tested these 12,000 hours”
Sunlike, have you considered Nichia V4 COBs?
According to my rough calculations, when underdriven they should deliver close to 140 lm/W at 85°C with CRI 9580.
If it has a blue bump I can predict the future: no
He’s already said that to other suggestions
I think in about two weeks I will be offering LED sources (E27,E14,GU10 5-9W) based on Bridgelux THRIVE.
The light they emit seems very pleasant 
Below is a basic comparison of the spectrum emission compared to Citizen 97 CRI and Sunlike LEDs:
Nice upgrade Bocian :+1:
BTW, do you intend to introduce some higher power dimmable bulbs?
I also think so but I thought it would be worth asking. I would surely find some uses for them…
TIL Citizen’s primary business is LEDs, very interesting!
Suppose their watch brand is more of a holding of the larger company like how “Seiko Epson” owns the Seiko watch brand as a tiny sliver of everything else.
BTW, I notice that the Citizen chart mentions CRI97min. But I only see CRI97typ on their website. What do I miss?
Interesting! I've been trying to keep an eye out for (reasonably priced) home lighting products made with their new Thrive lineup. My ultimate would be a zigbee-controlled CCT/dimming option. It looks like their Vesta series does 2700K-6500K, though frankly I never use above 5000K.
Where should I keep an eye out for more info? @bocian
