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

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

283

Not really a waste when you see whatā€™s inside. :smiley:
But i bought them to use the E27 base and the plastic bulb, soā€¦

284

Nice. :slight_smile:
I wouldnā€™t expect a light bulb maker to modify so many componentsā€¦

285

I expect that this is just prototyping.

286

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.

287

NO!

Every of my lamps!

288

Yeah, cheap Chinese electrolytic capacitors generally suckā€¦

289

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

SunLike, thereā€™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.

291

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

292

Theyā€™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.

293

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.

294

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

295

Just purchased some Feit LEDā€™s from Costco for $12.99 for a 6pk. 91 CRI, 90 R9. Canā€™t find them on Costcoā€™s site or Feitā€™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).

What state are you from elwood? Do you have any pictures of the packaging you could post? UPC #?

EDIT:

Are these it? https://www.costco.com/feit-electric-led-60w-replacement-soft-white-frosted%2C-24-pack.product.100482235.html

Iā€™m in Louisiana. Those donā€™t have the same specs. Like i said, i couldnā€™t find these exact ones on Costco or Feitā€™s website. The model number is CEOM60/27/6(W). Hereā€™s some pics of the exact same ones i purchased.

298

The Feit enhance bulbs on costcoā€™s site all have terrible reviews indicating bad caps and build quality, but as you said the models were different.

299

If I knew what to look for iā€™d be willing to sacrifice one to see if theyā€™re built any better.

Caps that are rated 105C or less, worse if theyā€™re not japanese. Good ones are rated 130, only 6 cents moreā€¦ Theyā€™re always potted with grey stuff, have fun with thatā€¦

Once had some overpriced chinese ones rated 85C (viribright) needless to say they die fast >_<
