Sunlikelamp.com SunLike10xss SOL Ultra High CRI E27 LED bulb (2700/3200/5000/5600K)

TL;DR
If you want the absolute pinnacle in LED color production for your home, get the Sunlike SOL E27 bulb.

The main specs by the manufacturer:
-CRI 98-99
-SmartEcoLightning SOL COB LEDs (also available with Seoul Semiconductor SAW emitters)
-1000 lumens, 10W power consumption
-AC voltage range of 220-230V or 110-120V, selectable when ordering
-No dimming
-No lifetime specified
-Unknown warranty

This bulb is huge. My version is a custom edition with four different CCTs mounted on one bulb. They can all be invidiually turned on and off. This done via small switches on the lamp. It took some experimenting to find out how the switches address which COBs are on. It’s not practical for everyday use, but to check all the options out at once, this was a good compromise.

The Sunlike bulb next to a 60W incandescent:

Normally the bulb just comes in one CCT per lamp. If you want to mix the tints, get a couple. But as can soon be seen, even minus duv fans don’t really need to. The tint is below BBL on all of them except for the 2700K, and even that is just barely over.

The huge heatsink with large surface area helps with heat and the bulb only gets to 58°C at its hottest point after an hour in the integrating sphere.

The plastic dome diffuser comes off easily off just by screwing it open. All the measurements were done with the diffuser attached.

Measurements

Measurements were made in a 50cm integrating sphere with an x-rite i1pro spectrometer after the bulbs had warmed up for 1 hour. Intensity (lux at 1 meter, candela) was measured outside the sphere at 1 meter.

The bulbs were connected to mains power which at the time of testing was at 227-228V.

Output at 1 hour depends on the CCT used ranging from 674 lumens at 2700K to 794 lumens at 5600K.

Power consumption is identical at 9.5W whenever only one of the COBs is active. With two it drops to 9.1, with three 8.9W and with all four on it’s 8,8W. Using 2-4 LEDs increases the efficacy from 71-83 lm/W to up to 92 lm/W.

Maximum output is reached immediately. Output was plotted over one hour using the 5600K LED. After 1 hour the output decreases just 7% thanks to the great heatsinking. Usually the drop is around 15%.

Color rendering

The CRI data was measured integrated after a 1 hour warm-up.

Color rendering and tint is spectacular on all LEDs. That is the reason for this bulb to exist. It’s up there with Nichia’s Optisolis when it comes to spectrum continuity. On lower CCTs the Sunlike is even better as Optisolis only truly shines on 5000K and up. This is the bulb to go for if you’re picky about your lights.

Below are the CRI measurements on the single CCT modes. Data and TM-30-18 reports for all the possible CCT combinations can be found from the album here:

Color temperature and tint

Tint is at or below the black body line on all CCTs except for 2700K which has just slightly positive duv. Remember that when LEDs heat up, their duv value almost always decreases and becomes less green/yellow. The great heatsinking seemed to be enough that the tint between 5 minutes and 1 hour wasn’t as large as usual.

The flat COB emitters don’t have much of a tint shift and the diffuser helps with that. Because the COBs lay horizantally flat on the heatsink, output is naturally highest directly below the bulb. There’s hardly any difference between tint measured directly below or integrated over the whole beam.
Tint shift was measured with the 5600K LED after a 5 minute warm-up period. The overall tint is more green than in the previous chart since the LED hadn’t completely warmed up yet.

Flicker

There’s no visible flicker. Just some minuscule ripple at 75kHz. Snob index of 0% guarantees that it’s easy on the eyes. The modulation depth was highest when all the LEDs were active, which as the worst case is shown below.

AC power draw

Current is drawn in short pulses as the input voltage gets high. This results in a low power factor of 0.57.

Cyan line: mains line voltage
Yellow line: current draw of the bulb
Violet line: power draw (voltage * current)

As a side note, the bulb can also be used with a DC power source. It turns on at a relatively low voltage of about 20 volts.

Verdict
What can you say. The Sunlikelamp.com SOL bulb is by far the most impressive one I’ve tested to date. With the perfect tint and smooth spectrum it is even better than Nichia’s Optisolis at low color temperatures. The massive construction and great heatsinking ability is also a big positive.

Please note that the test was done when the bulb was brand new. I can’t guarantee that they will perform similarly after months or years of use.

thanks! =)

But SOL it is SmartEcoLightning co. Not SeoulSemico..

It is LEDs from China, it is not TRI-R technology

It is 2700-3200-5000-5600k LEDs

Awesome.

Are the high CCTs like 5000 and 5600 pleasing to the eyes?

It measured quite far from 3200K though. All the others were very close to their spec. I’ll fix it on the text.

I ask because typical LEDs of that CCT hurt the eyes in a way sunlight doesn’t. Think florescent. I assume it’s a blue peak.
But maybe I am wrong about why and it’s more of a reference thing when you are indoors around different CCT.

That’s just it, these don’t have the blue peak. They track sunlight very closely.

I have only 1pcs in stock. But after 1 month I will have another 30pcs. It is not popular and I think that 3200k much better.

The LED bulb won’t give you a retinal sunburn or cause UV-related darkening of the eye’s lens, if that’s what you’re asking. It doesn’t emit enough invisible frequencies to hurt the eyes like sunlight does.

So… it’s not exactly like sunlight.

I guess it’s a matter of preference, but i prefer 2700K or a bit lower for indoor (home) evening lighting.
Let us know when you have them in stock, if you want.
I would buy 3 or 4 pcs of the 2700K 6 Watt SOL COBs

The results here look really really good.

I would love to get a bunch of those in ~4000K.

4000k is most popular. And I like it more than others. But 4200/4300k is better. I will have it when I will mix 1pcs 5000k and 2pcs 4000k 3030 smd LEDs sunlike.

If someone ends up with the same bulb and wants to try out all the different combinations, here’s what works.

Note that there are other switch combinations which result in the same COBs being on, but this is just one that I first wrote down before testing and is not necessarily the most logical one. Going through the color temperatures is a bit more intuitive once you get your hands on the bulb, but it’s not super user friendly. This could use a remote or an app Wink

If it says 3 up, it means all the others are down as there’s only two positions.

Looking from the side so that the bulb is facing upwards.

Single COB
2700K All switches up
3200K Rightmost switches (5+6) down
5000K Center and rightmost switches (3+4+5+6) down
5600K All switches down

Two COB mix
2700+3200K Switch 6 down
2700+5000K Switch 4 down
2700+5600K 1+2+3 down
3200+5000K 3+5+6 down
3200+5600K 3 up
5000+5600K 1 up

Three COB mix
2700+3200+5000 4+6 down
2700+3200+5600 3+5 up
2700+5000+5600 2+4 down
3200+5000+5600 1+3 up

All COBs on
2700+3200+5000+5600 2+4+6 down

Yes, that seems confusing, but actually not so. Cycling modes from warmest to coolest in succession without going through all the possible mixes is easy. From all the switches up, just keep pressing the switches down starting from the right one by one and you end up with seven steps, which should give you the desired CCT.

I will not do 9s model anymore =) It was unique – for rewiev SOLs LEDs from SmartEcoLightning co. (it is with the BEST spectrum in the world, better will be StarLike LEDs, but I didn’t tell you this, it is secret) Better than SOLs can be more cheaper LEDs with the same or better quality, but price of leds is not feeld in final price of my bulbs.

But when I produced this model, it was good idea in my mind: I will do S model (13s) with 4 switches, not 2 like in past, and it will be with resistors on it (ordinary and NTC). Previous idea was to use NTC resistor (because with ordinary it will be too much energy when all curent will go to line with resistor) with 2 switches for 4300-4200k middle mode. With 2 switches it is 3 modes, but with 4 switches and resistors it will be 2 types of leds and 9 modes (not 3) with ~2700-3000-3700-4000-4300-4600-4900-5300-5600k

Now I am waiting for NTC resistors to do model in real.

If someone want MORE PHOTOS of SunLike10xss
upgade of LED drivers v1.4

What inside SunLike10X (SunLike9) model? It is most cheap LED bulb from me
Without any tapes. I isolated body with mica

How much time need to produce SunLike6C?

How much time need to draw pcb board?

How much time will work ordinary LED bulb and why is so short life time?

I am going to have to measure my desk lamp to see if one of these can fit. I am a bit concerned about the size and weight though since it’s on one of those spring tension arms. Super high CRI, nice tint sounds like an ideal light for this type of application.
