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.
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
If someone want to buy some REMEZ bulbs with international shipping ($6 for any order) or find out the price, you can do it HERE
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?
