Ultimate LED Bulbs - Ultra High CRI - The Honorable Quest

Update on Ultimate LED Bulbs - Ultra High CRI - The Honorable Quest - #236 by Dalamar

I had to repload the CRI result… the image was missing, implying they may have DMCA’d it, but never got a notice from google… I would not buy from that aliexpress store with the way they bully, the only way that image went missing is they reported it.
They sent me “tests” with numbers very different from my old and outdated calibration tool (which only has a problem with too much green) on aliexpress…. (and of course, it was only “tested for 2 months”)

DIY led uhome if you are reading this it never pays to be a bully!

regarding the heat comment… it creaks when turned on, this implies that it is heating rapidly. so clearly there may be an issue, I have no way to measure the temperature.

TL;DR

It is as advertised but nothing spectacular. The CRI is not as high as Yuji or Waveform type 95+ CRI bulbs but the output is nearly double and price slightly cheaper. These types of filament bulbs are probably your best bet if you want to use a dimmer though I did not test that yet.

Thanks, that one looks good for the price.

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.

FEIT Electric OM60DM/930CA/4
$2.47/bulb

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.

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: :wink: :smiley:

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…

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 (tssss, it is the secret):

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?
