Sunlike 13SS E27 Adjustable CCT Bulb (2200K-5600K, CRI97)

SunLikeLamp.com sent me their adjustable CCT LED bulb for testing.
Manufacturer website: http://sunlikelamp.com/index.php?route=product/product&path=59_63&produc...

This large and relatively powerful E27 bulb from Sunlikelamp.com has two different CCT COB LEDs with micro switches to adjust the color temperature between 2200 and 5600K (5 modes in total). While the exact LED configuration tested here is not available from the webstore (for a good reason), it’s available with customizable color temperatures with different methods for switching between them (power cycling, ZigBee+remote). There’s a variety of other options as well such as more LEDs, different bodies and lenses.

The main specs by the manufacturer:
-2200K-5600K color temperature (five modes total)
-Chinese SOL COB LEDs
-CRI 97
-13W power rating
-AC voltage of 85-285V, also available as a 3-35V DC version
-lifetime estimate 20 years
-warranty 11-22 months depending on payment method

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. Tests were conducted without the diffuser unless stated otherwise.

The bulbs were connected to mains power which at the time of testing was at 230V.

Output at 1 hour on the middle mode with all the COB LEDs active is 1071 lumens at 12.4 watts. Manufacturer doesn’t specify output.

Efficiency is alright considering the very even spectrum and high CRI. The warmer LED is significantly less efficient as is expected.

Maximum output is reached immediately. Light output in lumens was plotted over one hour. Output drops only a little during the first hour and doesn’t take long to plateau. Output is perfectly stable regardless of house AC voltage fluctuations.

Color rendering

The CRI data on all the CCT modes was measured after a 1 hour warm-up period in an integrating sphere without the diffuser. The actual tint and color reproduction will be affected by the light fixture and the color of the room.

2×2200K

5600K+2×2200K

2×5600K+2×2200K

2×5600K+2200K

2×5600K

Color rendering is very good reaching CRI Ra of 97-98 when only one type of LED is used. The warmest mode produces similar results to the previously tested Sunlike 3-5 bulb using the same LED.

The color temperature difference between the 2200K and 5600K LEDs is very large. Mixing them reults in a lower color rendering index and mixed modes are also very pink in tint for the same reason. On their own, none of the modes look bad, it’s only when you’re switching between them when the difference in the tint (pink/yellow) is obvious and distracting. Going to the warmest mode from any of the mixed ones results in a visually very yellow light.

2×5600K + 2200K
2×5600K

Color temperature and tint

Tint is slightly above the black body line on the 2200K LED and slightly below on the 5600K. When LEDs heat up, their duv value almost always decreases and becomes less green/yellow. This was measured after 1 hour in an integrating sphere when the output and tint were stabilized.

Because of the large CCT difference, the middle modes are pink in hue as their xy coordinates on the CIE chart are exactly linear.

Tint shift is not an issue with or without the diffuser thanks to the flat COB LEDs which rarely exhibit significant shift with varying observer angles.

If you want to see how the diffuser affects the color, here’s a comparison from directly below the bulb at 1 meter with and without it.

2×2200K

5600K + 2×2200K

2×5600K + 2×2200K

2×5600K + 2200K

2×5600K

Flicker

Flicker is not an issue. Slight ripple at ~50kHz and a snob index of 0% guarantees visually stable output.

AC power draw

Current is drawn in short pulses 100 times a second as the input voltage gets high. Power factor is low at 0.56-0.58. Color temperature doesn’t change the behavior and all modes consume pretty much the same amount of power at just under 13 watts.

2×5600K + 2×2200K
Voltage: 230V
Current: 0.097A
Power: 12.4W
PF: 0.56

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

Noise

There’s no audible buzz or whine from the bulb.

Verdict
The Sunlike SS13 is a large and powerful but well heatsinked E27 bulb for home use. It features adjustable color temperature too. My sample had an unfortunate mix of LEDs which make the mid modes quite pink compared to the extreme ends but better configurations are available. Choosing 2700K+5000K for example will be much better in this regard. Color rendering and tint is very good as the previously tested SOL series of COB LEDs have shown.

Switching between color temperatures either with power cycling (turning the light off and back on again) or using a Zigbee compatible remote is a more convenient alternative to the microswitches in my sample. Especially if there are more than two different CCT LEDs used.

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 for the review, too bad the tint of the 2200K COB is above the BBL, I’d like to achieve arround -0.005 at 3000~2700K but it looks like mixing it with 4000K Sunlike SOL (that I already have) it’ll only do arround -0.0020.

Have you recieved yet the 1700K 36V COBs that were mentionned in the Convoy thread ?

They could potentially be interesting for color mixing, if they don’t have a Vf too dissimilar.

They declined to send a sample for review.

I think best choice will be mixing 2700k and 5000k

This 5600k was from another box with samples in SunLike10SS what was tested by Maukka some earlier in this forum ..

Some rose tint is good for beauty shop or brothel. May be someone have his own brothel? Love

Like most people I don’t mind the -0.0100 duv at all on its own, but if there are other more neutral light sources around, those end up then looking way too green.

About 2250k. I ordered it to do bedtime light. It is not standart spectrum from SOL manufacturer (Smart eco lighting co.)

Maukka, thanks for review! I will waiting for 18LD review Cash

p.s. All my models 12+ watt are dimmable

Check This thread

You can use a spectrophotometer like the Xrite i1 pro (the one maukka uses) that can be found second hand arround 250~350€, or the Xrite i1 studio which can be found new for 350~400€ (I bought mine 360€).

With ArgyllCMS (free) to capture the spectral data and display tint and color rendition info, then you can load the spectral data in Osram color calculator (free) to get more details and export TM-30 reports, also calculate color mixing which is quite fun (that’s where I got my estimation of mixing this 2200K with 4000K SOL, you’ll also see with it that mixing with 2700K won’t lower the duv enough to get what I want), and other stuff.

there is also Argyllpro (100€) to use the spectrophotometer directly with an android device, which is certainly more user friendly and faster.

I understand, but I also manufacturer of grow led bulbs and lamps

Also I am going to produce really powerfull and eternal lamp for extended nails drying.
Spectrometer must be from 360nm (usually spectrometers starts from 380nm)
And there is SunLikePLUS spectrum with IR

and StarLike™ also with much IR

Ah alright, indeed the ones I cited have a range from 380 to 730nm.

FWIW, I’ve been doing research on what’s out there for legit Spectrometers. Here’s a google sheet for reference.

Excuse me, but I already chosen =)

Because I am almost official dealer of UPRTek with goood discount and I like their soft (program). I choose PG200N for my lamps. Yes, price is really expensive (2800$), but for me it will be special price (I hope)
