Ultimate LED Bulbs - Ultra High CRI - The Honorable Quest

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

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

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

I’m in Louisiana. Those don’t have the same specs. Like i said, i couldn’t find these exact ones on Costco or Feit’s website. The model number is CEOM60/27/6(W). Here’s some pics of the exact same ones i purchased.

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

If I knew what to look for i’d be willing to sacrifice one to see if they’re built any better.

Caps that are rated 105C or less, worse if they’re not japanese. Good ones are rated 130, only 6 cents more… They’re always potted with grey stuff, have fun with that…

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

Ok, i’ll crack one open after work and report my findings.

It wasn’t potted. Just a little bit of crunchy glue (epoxy?) holding the driver in place…

Chinese put meaningless markings… you never really know the real values… even Adam’s chinese sunlike have inaccurate document/rating according to him…I don’t trust chinese electrolytic capacitors. Probably why the reviews are so bad.
Even if they “can” last advertised ratings, Chinese products have a higher error rate than Japanese. USA-made suffers a similar problem sometimes, misleading measurements…

Not necessarily saying its bad as there isnt much info on the new brands, but China loves to rebadge stuff…

I bought a 4 pack of the “100W” equiv Feit bulbs from Costco a few weeks ago. I could probably get spectral readings one of these days.

On another note I bought some of these EcoSmart brand “filament style” LED bulbs with clear glass casing. Color temp of 3000K is really nice and they dim with my cheap Lutron dimmer with NO BUZZING. It’s a miracle. I’ve tried like half a dozen bulbs with this dimmer and they all buzz so that is very exciting even though the bulb might only be 80CRI, need to test it as well.

At around $2/bulb i’m definitely willing to give them a shot. I’ve been searching for a while and i’ve yet to find any other bulbs even near this price range with this CRI/R9 and dimmable.

That being said, i would’ve gladly paid slightly more for better electronics. I wish these could be opened up without destroying them. It may be worth it to swap the caps.

I was worried about dimmability too. The Feit’s dim with no issues on my Caseta dimmers. They just don’t get quite as low as my recessed lights. I’d say about 10-15% dim.

I believe the Feit’s buzz a little (like most LED bulbs to be honest) but really it’s only an issue on bathroom lights for example where it’s quiet and you commonly have down facing globes right next to your face.

Thanks for the tear-down elwood. I’m going to visit my local Costco and see what they have.

Another thing that I’ve been debating is to just modify all of my Walmart brand LED bulbs. Every one that I’ve opened so far has used 9 series 3030 mid-power chips that share a footprint with Optisolis. A couple of strap wrenches and heat from a hair dryer twist of the plastic diffusers which are held by a white silicone. Problem is I don’t have enough Optisolis emitters right now to even do one bulb in a low CCT.

Damn,I have allocated some time to search for DIY parts to build similar “sunlike” led bulbs. And only now realized how big that bulb would be… Seems 7W-9W (based on sellers specs) is the biggest TDP I could afford while purchasing Al LED bulb shell. That plastic diffusor on powerfull led bulbs takes too much space.
