Ultimate LED Bulbs - Ultra High CRI - The Honorable Quest

It could go up to 2 Watts in that set up and stay cool enough with that heat sink, but the drivers turned out to provide only 450 mA in stead of the promised 600 mA.
But it’s the right amount of light for a bed side light.
I estimate it reaches around 45°C under room temperature conditions.
The little sphere lights up nice and evenly, despite the LED sitting at the bottom.
Light loss due to the white plastic of the spheres is much less than i expected.

I think you will like this types of bodies

What the actual crap…

If there were any heatpipes in the design, I would mistake this for a CPU cooler lol.

Anyway, is your desk this cluttered, is it just my impression?

Now I want a bulb with a noctua nh-d15

as you wish

Jerommel, I need diffuser spheres like the ones you used, where did you get them?

Thanks. Seems like a waste to throw away the rest of the bulb… I think I will raid the nearest bulb recycling bin.

Are you interested in a teardown of OSRAM GU10 CRI90 and CRI97 bulbs?

Not really a waste when you see what’s inside. :smiley:
But i bought them to use the E27 base and the plastic bulb, so…

Nice. :slight_smile:
I wouldn’t expect a light bulb maker to modify so many components…

I expect that this is just prototyping.

To anyone recycling the driver of dimmable E27 LED bulbs BTW:

Just replace the capacitors with higher quality and better rated ones and put a thermal pad on where it can touch the enclosure.

I recently got a few dead bulbs, and got around to removing them, and man, some of those bulbs either use solid aluminium heatsinks with no fins(so much mass though), or pure thermal ceramic for heat transfer.

Only problem? Their caps died.

Other than that, cheap low CRI dead E26/E27 bulbs are good candidates for modding as long as you replace the LEDs and capacitor.

NO!

Every of my lamps!

Yeah, cheap Chinese electrolytic capacitors generally suck…

CBB capacitors is cheap too. But it will works years and years

SunLike, there’s one thing you could improve about your store. Provide efficacy numbers.

F.e. with 50W bulb I can choose to have 1 or 2 COBs and you say that the latter is 15% more efficient but costs 32% more. Higher efficiency sounds good but being able to quantify the improvement would be a major factor in making the decision.

Thanks for your submissions, I added those bulbs in the table.

They’re a lot bigger for the same capacity though, which can be a problem.
But you can buy Japanese brand elcaps, they will last long too.

Prometheus Lights will be selling a high CRI bulb.

The 2700K version has a DUV = -.0.0006 which is not negative enough for my personal preference but I think many will like it.

400-450v CBB is not so big, but 100v (there is no big capacity with 63v and 63v it is minimum voltage) really much bigger than electrolytic capacitors
