Ultimate LED Bulbs - Ultra High CRI - The Honorable Quest

what?! :open_mouth:

World government will kill me if I will mass produce bulbs like that

Now only like this in my shelter:

Wow amazing results!

Even with a price reduction from economies of scale, I think they’d be a lot more expensive than the average person is willing to spend on a light bulb.

I remember SunLike speaking of these bulbs being designed to last a very long time. If my memory serves me well he spoke of 20 years.
Now I’m convinced that I want to have some but expected durability is a big factor in the discussion. If I can expect 5 years, I’d buy a few for fun uses. If I can expect much more I’d buy a larger volume.

Can someone independent who has a good idea of electronics share their thoughts on the topic?

If you had to guess, what would be the first thing to die in one of your bulbs? The LED or one of the driver components?

I have three or four LED 110v household bulbs that have died, clearly a driver component (multiple emitters visible, none damaged)
All of them are glued shut.

My brother gave me a small hair trimmer whose batteries were dead recently, it was refusing to work with a blinking red light. You could make it work by first plugging it to the power supply, turning it on and then disconnecting the supply's cable, but refused to work by itself on batteries. Its electronics raised the end of life flag, this means even if I had replaced its cells the thing wouldn't have worked.

On the other hand, I have a cheap hair trimmer which I overhauled with li-ion cells years ago, tuning its charging voltage for everlasting life. It also is noticeably more powerful than stock.

So, what are we paying for and why are we paying for?

People should completely stop buying carelessly, stopping this insanity.

I prefer to make good stuff. Anything which purposely reduces your vibration or that of what you do, is a disservice. As a consequence of looking at self interest beyond the highest good, it is skewed and leads to crash. Like being on drugs.

CRI remarkably decent on these, though price is too high for what they are.

Like many of you, searching for a high performing 95+ CRI 95+ R9 LED bulb under $25 US - very difficult, it seems. The performance of even 90 CRI bulbs isn’t good enough for my eyes, colors washed out and ashen - yuck.

  1. Has anyone tested the Philips ExpertColor line? They claim 95 CRI but I don’t see any R9 or Rf performance.

  2. How about the Soraa Vivid line? I recently purchased several 2700k and 3000k - very nice R9 performance. Reds really pop but they are terribly expensive at ~$60 US for Par30.

Most of the sunlike bulbs are under that price

I have MASTER LED ExpertColor LED ExpertColor 5.5-50W GU10 927 36D 871869670767800
in warm white
CRI (Nom.) 97
they are very nice also the tint is good but I can not test things like CRI or R9

Soraa lamps is nice by CRI & R9 , but tint isn’t ideal ; excellent heatsinks (I use AR111& mr16 lamps). And “violet pump” instead of blue.

Philips ExpertColor line — 95 CRI for E26/27 lamps , 97CRI for mr16/gu10 lamps.

> Soraa … but they are terribly expensive

Yep, I’m hoping the price falls on those over time. I can wait.

Anyone measured flicker on Philips LEDspot ExpertColor GU10 ?
On Amazon I see few reviews about flicker,_
“However, there is a very small amount of flicker both at full brightness and when dimmed,
which is disappointing as some cheaper LEDs don’t flicker at all. ”_
and “Actually nice warm light with good color rendering, but: It flickers!
It is impossible to take photos with a digital camera (Lumix G5) or even with a mobile phone, because everything looks striped. ”

Can you measure temp. of these lamps (thermometer, thermal imager ) after 1 hour work?
How much flicker on full power or when it’s dimmed ?

One more warm white CRI95+ bulb tested here:
Prometheus A60 E27 LED Bulb (2700K, CRI96)

I ordered several bulbs from Bulbrite from the below criteria. Mostly filament bulbs because they seem to dim extremely well and have good side output.

Bulbrite product search

I guess this is the same company who makes SORAA to i’m hopeful they are good. I will run basic spectral tests when they arrive.

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.
