Received few gu10 and mr16 ExpertColor lamps from Ebay store’s.
Very nice tint, may be slightly better, that from Soraa Vivid 3000K.
Good optics (36 grad).
Color reproduction - very nice for LED lamp (not as good , as from my etalon bulbs, Osram halogen 3000K and Solux halogen 3500K, but very close and better than many other CRI90+ lamps).
Temperture after 25…30min of work :
gu10 5.5w 230v : approx. +50…+53 (Seek Thermal xr),
6.5w 12v : approx +61+63, +60 on foto, 1min after off and removed from fixture (ambient temp. : +20 …+21).

1) philips Expertcolor gu10 5.5w in open fixture, Wofi Minit , after30min
2) philips Expertcolor mr16 6.5w in Ikea desk lamp
3) || 1min after off and removed from fixture

What is the easiest E27 high CRI bulb to acquirer in the UK, without high costs?

I have the Philips ExpertColour GU10s in some places, but they don’t seem to have a ExpertColour E27.

I am going to do an experiment. I have a ton of Lee minus Green (804). I am going to see what happens if I open these up and add a minus green filter to them.

Here’s an amazing tunable high CRI bulb of the “future”. Tech would need to trickle down to households but it’s an interesting read.

Just purchased some Feit LED’s from Costco for $12.99 for a 6pk. 91 CRI, 90 R9. Can’t find them on Costco’s site or Feit’s. I can tell a significant difference in the color of my walls in comparison to my 80 CRI recessed lights (need to find replacements for these next).

EnergyStar specs

Update: I’ve replaced 6 bulbs so far because of major flickering issues (at full brightness or any range). Disappointing.

I’ve contacted their customer support to see if they’ll send replacements.

When you say full brightness is it still on a dimmer? I could never get the flicker out on my dimmer either and Lutron are regarded as some of the best dimmers for LED

These particular ones are on a Lutron Caseta dimmer. PD-6WCL i believe. I have no flickering or anything during dimming, they get really low before just simply turning off. They’re just randomly failing, probably crappy caps.

But it only allows changing CCT, which already exist. I wish it allows tweaking DUV also.

It can tweak to Duv as well and even adjusts based on LED age (by detecting fwd voltage) to maintain 1 step eclipse. It can dim through wireless commands or via in wall dimmer which detects waveform.

I love improved tech, but this sounds like it crosses a line into overly complex.

Are there any R7S LED bulbs worth recommending?

Interesting name. Feit. Fate. Ill fated? :person_facepalming:

I’ve really been out of the hobby for lack of time since early May… Just moved into a new house and as any true lighting snob would, despised most of the bulbs/fixtures currently installed. Really wishing a truly good and affordable bulb becomes available soon. I still have a handful of Great Value bulbs waiting to get emitter swaps with SunLike 3030s. Also have really been desiring a truly good variable CCT (but not RGB) bulb. Ideally a smart bulb (circadian) that has a time/calendar/latitude programming maybe via BT or even one-time flashing via USB…

p. IKEA Ledare, type LED1708R5.
A dimmable GU10 bulb that uses very warm leds at the lowest brightness setting and gets cooler tint at higher setting by gradually mixing in a cooler set of leds and switching off the warm set at the highest setting.

Gave the 600 lumen version of these a try, and it seems to have mad tint shift. The edges of the beam are outright orange on this set of them. I’m also getting more glare than I expected, but it might be just the beam being a bit narrower (36°).

That being said, found a 3000k Luminus 50W equivalent dimmable 90+CRI 40° GU10 claiming 71 lm/w (as opposed to the 80 lm/w that the 600 W Ledare claims) that seems to be pretty good.

Not seeing it online, but the model name in-store was Luminus Elite+ LED.

StarLike LEDs is near!

I’d be very interested to hear more about these StarLike bulbs. Is this the next evolution of your SunLike bulbs? Still using the Seoul/Toshiba SunLike 3030’s/COBs?

Lidl have some E27 2700k 806Lm bulbs £3.49 for 2 pack. They are advertised as Ra >=97 but they are just an awful yellow hue, not the normal white/orange but more a bright yellow colour.

I’d like to make a web app for this list that is a searchable, filterable list and includes spectrum data/charts. Right now I’m using the X-Rite Colormunki Photo, but I’d really like to be able to chart beyond 730nm. The much more expensive Sekonic meters only go to 780nm. The only competing product I’ve found that goes beyond is an aliexpress find for $1550 called the Hopoocolor OHSP350S that covers 350-950nm, or they have an integrating sphere setup with sensors that cover 200-1100nm, model HPCS6500, for the low low price of $7k.

Any options that I’m not aware of that would allow accurate, repeatable capture beyond 350-750nm?
