Ultimate LED Bulbs - Ultra High CRI - The Honorable Quest

“Remez” brand offers led bulbs on Seoul 3030 sunlike LEDs.

“En” version is not ready (https://remezlight.com/en/).
All led lamps on “ru” site are in preorder (https://remezlight.com/production/led-bulbsz/) and no international shipping.

I’ve had terrible results with most LED bulbs I’ve purchased… well ever. I have a couple brand name units which are going strong but most of the normal replacement LED bulbs (is it A19?) seem to fail in the same or less time than the old incans.

I’m not super picky, just looking for something which will last, is affordable and offers 4000k or warmer with 80 or better CRI. Is there any particular “go-to” replacement bulbs which would fit this requirement?

Only DIY… unless you’re using low power “commercial” bulbs (usually max 600 lumen) rather than off the shelf “consumer bulbs”. The package can’t dissipate the heat, and many consumer bulbs are built to fail.

Some DIY implementations are pretty easy and simple…$500 photographer panel for $72 parts, but tools are always needed no matter the route

Honestly, I’ve used Walmart’s Great Value brand 2700K 60W (and a few 80 and 100s) almost exclusively over the years. I’ve bought dozens of them and never had a single one fail during use. Maybe I’m lucky, but I think they’re pretty reliable.

As for CRI, I don’t know where they stand. Tint from revision to revision has varied above and below the BBL, but never really objectionable. Warm white mid power emitters probably have 80ish CRI as standard I’d guess as <3000K black body curves are much easier to replicate. I’m going to swap one of mine to Optisolis and see how it compares in the real world. Just waiting on a shipment…

Buy a name brand and keep your receipt + the cardboard part of the box. Philips stood behind their warranty for me i’m sure the other big name brands would too. I’ve also taken a current model CREE bulb back to home depot and exchanged it for its same model with no receipt. It’s rather absurd to say no consumer bulbs are good.

The fixture, line power, weather, and a dozen other variables come in to play as well when it comes to the reliability of these bulbs. I think initially and to some extent still these are marketed as lasting a “lifetime” or never having to replace them in order to justify their higher cost but it’s simply not true.

Hyperikon delisted their 1600 lumen bulbs from amazon for a reason… landlord said major manufacturers didnt want to warranty unless he paid thousands for whole house regulation

Thanks, just added to the table. Hope we'll be able to have independant testing for them in the future.

Can somebody summarize for me the whole Costco discussion, do we have there a new ultra high CRI candidate?

No, they are like 92 CRI, ~60 R9 and dimmable but considering those specs they are quite cheap and represent a good value. Not a new ultra CRI candidate though.

The one’s i purchased are, supposedly 91 CRI, 90 R9. Just saying :slight_smile:

I do agree though. They’re not ultra CRI but at just over $2/bulb they’re an excellent value.

Now I am dealer of the REMEZ =)
With price like in official site (10-20% highter)
I have international shipping, but now it is 6$ for any order (by belpost)
About time of life of REMEZ bulb… 30000 hours… How they test it? Just by 1000 hours =)

You can buy REMEZ LED bulbs with international shipping HERE

Does it support 120V, seems like it doesn’t from their site? Also, too bad about no dimming.

I just taked results of the SmartEcoLightning (who do SOLs)

I am going to do bulbs with their LEDs with UV and IR for plants (additional light). But it will be for eyes too. It is with extreme hight CRI too. I am going to do 6, 12, 18, 36, 110W

I will send it to Maukka for test. They do not want to send it now. I mean for free. They concentrated in Russia market now. So, I will do it.

Also I will do review on my youtube.

1st. - Big aluminum body-radiator.
2nd. - 130° capacitors.
3d. - high CRI LEDs with all spectrum. I mean hight CRI in all R1-R15 indexes.

Just put some in my basement fixtures. Tried the 5000k but they were… just wrong. Too harsh. The 3000k rated ones (which feel more like 4000k to me) are quite nice, though. While not ULTRA high CRI, they are very decent and certainly heads and tails above most other commonly available LED or CFL bulbs. Typically our basement bulbs last a long time due to limited use, so might not be the best test of durability but we’ll see. I did date each bulb on the base in sharpie.

Alright I spent $99 on this Android app cause I was too lazy to install and carry a laptop all around my house for you guys. :beer:

NOTE: the only one I allowed to “warm up” was the 100W Feit, all the rest were on for less than 1 minute.

Cool app! I don’t see anything like that in the Apple store, though :frowning:

It’s only for Android and it works alongside a USB device (color or spectral meter) plugged into an OTG cable. In my case the cheapest one, a ColorMunki Photo (now sold as: X-Rite i1Studio) I got off eBay second hand.
