As far as I can tell the biggest difference in them is that they probably emit more light towards the base of the bulb so for certain fixtures designed for incandescent where you want the bulb to light up the entire fixture/shade they probably work better than the usual “front loaded” LED replacement bulbs.
Just a heads-up of another possible entry: our local LIDL had a bunch of different Livarnolux led bulbs manufactured by OWIM Gmbh advertised as Ra>=97 at 2700K for 6.99CHF (about 7$) for a pair. I bought 3 sets of 60W equivalent bulbs (810lm) model 312396_1904 (on owim.de website) with 9.5W consumption (not very good efficiency at 85lm/W). Unfortunately I don’t have any measuring equipment.
Some pics:
As you can see, it’s the usual plastic base with likely bad dissipation, but it does get quite hot during operation.
@fneuf, I just noticed your OP says (with french?) CRI_Grade is somehow related to the “à la energy efficiency norm”? that you linked. This is really confusing. CRI_Grade should not be explained with a comparison to energy efficiency. How about this:
“CRI_Grade” is an initiative to Grade lights based on their color rendering, but with extra significance given to the weakest areas of modern LED technology.
If someone want, there is REMEZ review from me (rus language)
there is some photos:
e14 5w & 7w and E27 7w works with 110-120v with ~1% pulse (measured by RADEX LUPIN)
E27 9w with 110-120v pulsed on ~25%
all of these works with 80-100v, but throbbing about 50%
in 9W there is 3.3uf, I upgraded it to 4.7uf, and now it works with 110-120v with ~1% pulse

Tests of all types SMD3030 SinLike 6v with diffuser from GX53 + mixing + SunLikePLUS spectrum (growing and healthy for eyes) + cheap FAKE white LEDs + LED TV
All of those sunlike emitters look super impressive on paper. Do any of them look significantly better to your eye? At Rf+Rg = >195 , is tint and CCT the only perceivable difference? I’m really curious if the SunLikePlus has any noticeable effect in the real world?
I’m not expecting them to look any better than the hyperikon bulbs they are replacing (those already look very pleasing to my eye). I’m mainly getting them because they should last a lot longer and should be healthier for my eyes in the long term.
Thanks for the pictures SunLike, but I’m not sure what the light sources are between the two photos? Obviously there’s a warmer CCT on the right with very good red saturation, but no clues to exact LEDs.
Thanks for updating that. I think maybe I didn’t ask my question clearly, I apologize.
I understand there are HUGE differences between the SunLike LEDs vs any standard CRI “white” competitor. Your pictures illustrates that well.
What I’m wondering is if there is a visible (human eye only) difference between SunLike Plus and SunLike 12S in 4000K? The spectrum is radically broader, but do these far out wavelengths have a significant impact to our visual perception?
I have a client who added a red-coated incandescent lamp (which gives red light) to a 4000k SOL. The camera responds well to this. Reflected red becomes larger. A perfect red gives an incandescent lamp – there are a lot of red in it. Personally, I have not yet tried to install such lamps at home. So far I have made 6C and 7w kit and 16 watts with SunLikePLUS LEDs, and they are with reflectors.
pictures from my buyer who add red:
Fixed white balance: SOL4000k | incandescent lamp | SOL4000k+incandescent lamp
It would be appreciated if someone told me how to get a proper spectral graph out of argyll…god I hate cli.
ColorMunki does not work with CT&A, although I found 5.0 on the seven seas…
It depends what you’re looking at. Cyan, violet, red colors of the variety you can find on natural things can be drastically different with the Sunlike SOL.
My collared dove neck highlight looks rather bland under my Cree light Cree 1600 lumen 5000k ta21-16050mdfh25-12de26-1-11.png - Google Drive , but under the mix of halogen/sunlike the neck highlights look a lot less dull. Manmade stuff you generally won’t see much different….
Sunlike’s cri comparison photo looks like a 80CRI with bad R9, which isnt really a fair comparison…
