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?)
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.
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.
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.
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.
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
They are in PL as well. I considered them until I saw some CRI97 lamp (or bulb?) that they claimed to make over 150 lm/W at very low price.
I don’t trust their ratings and I won’t buy them.
I’m shopping for similar lights…and I chose to go with simple lights that are based on E27 bulbs, either for all or for most rooms, not sure yet.
The reason is that:
The part that fails from time to time is inexpensive and easy to replace
There’s a lot of choice of CRI97+ bulbs as well as bulb-based fixtures, but nearly all fixtures with LEDs have just CRI80
I consider some of the bulbs that over-saturate colours for the dining room, good luck finding one with LEDs already installed
Though I like how the diffuser is uniformly lit in LED-based fixtures. And for that reason I consider buying a fixture and filling with LED strips. Though it’s more work, not so easy to replace (still quite OK) and actually there are fewer good strips than good bulbs.
