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

Based on their published data from their website, its 170v mini.

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.

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


Triple pad LED? Are they high power? Maybe they would be suitable for flashlight use?

Though spectrum looks worse than the COBs. For bulbs, what advantage do they have?

It is for plants. Real power is 1.2w. Size is 3.5×3.5mm. You can solder it on standart cree star.

Also they will do COB with the same spectrum 19×19mm 14w.

Also this leds can be used for eyes. It is universal. For plants (additional light) and for eyes. It is the reason why I will do bulbs on it.

I will call it SunLike PLUS, after that will be StarLike (it is a sicret now)

Weak. But if it overdrives well it might be a feasible E21A alternative….

Thanks.

Can you measure max.temp of back surface of these lamps ?
for example, at open air at room temp, and , may be, in some ceiling lamp.

Flashlights : custom (Jaxman E2L with led4power LD-4 drivers and 3xOsram CQAR.CC), custom Skillhunt H03 with Osram 3К/4К, Zebralight {H600fc IV, Sc600fc IV, H600fc III}, Jaxman E2(N219b), Convoy UV.
Previous: Zebralight {H501, H600W, H600W II, H602W}, NiteCore TIPCRI, A A01, Fenix L2D CE/CEQ5.

Found the best “Candelabra” I’ve seen yet:

EcoSmart
60-Watt Equivalent B11 Dimmable ENERGY STAR Clear Glass Filament Vintage Edison LED Light Bulb Bright White

CCT 2990.3
CRI 92.3
Duv 0.0007
R9 59.5
Rf 87.8
Rg 95.1
R12 80.2

It’s a glass filament style bulb and dims down to what I estimate to be only a few percent. It honestly looks like incandescent low dimming, crazy.


Also tested a Feit 4ft tube light from Costco.

Meh, better than GE in all aspects including price but still looking for good high CRI one that isn’t crazy expensive.

CCT 3848
CRI 83.7
Duv 0.0018
R9 15.9
Rf 82.7
Rg 94.9
R12 61.4

Are these “vintage Edison” style LED bulbs as efficient as COB or SMD style emitters?

100lm/W probably about right for 90CRI. There is a ton of phosphor so I imagine it makes up for lack of efficiency

Great, thanks. I saw some for sale at my local Shoprite. Just $0.99 for 60w ones, but non-dimmable.

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.

Hi guys,

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
