Bocian custom 98 CRI 12W GU10 LED spotlight THRIVE solarlike spectrum

Bocian custom 98 CRI 12W GU10 LED spotlight THRIVE solarlike spectrum
Custom MR16 / GU10 spotlight based on a Bridgelux THRIVE COB emitter with a CRI (Ra) 98 textured reflector optics. Instead of the default, transparent protective glass, you can install a diffuser (included) made of satin plexiglass (frozen effect). CCTs available: 2700K, 3000K, 3500K, 4000K, 5000K.

The total power from AC mains is 12W (90-277V input). Lights based on the 20-25W COB THRIVE LED variant. During heating in room temperature, the aluminum housing reaches the temperature of ~ 60 ° C. The COB emitter is powered by 320mA with a forward voltage of ~ 34V, which gives ~ 10.9W of LED power. Brand-name, high-efficiency driver with a number of protections. The power supply was additionally modified in order to maximize the projected lifetime – added NTC soft start, additional low ESR, long life capacitances) The total measured drivers efficiency is ~ 90%. Power Factor min. 0.5. Driver with a fast output – NO FLICKERING EFFECT (e.g. visible in the camera). Not dimmable. The emission angle of the optics with a transparent glass ~ 45 degrees (with a diffuser – much wider) Smile







The set includes CNC milling machine made, satin plexiglass diffuser (the light transmittance declared by the manufacturer is 70%).

Below are the typical parameters of the quality of light generated by Bridgelux THRIVE emitters and a comparison to CITIZEN 97 CRI and SUNLIKE SSC:

Dark anodised aluminum housing.

Below available CCTs and luminous flux*:
12W 2700K THRIVE 98 CRI – 1084lm
12W 3000K THRIVE 98 CRI – 1164lm
12W 3500K THRIVE 98 CRI – 1213lm
12W 4000K THRIVE 98 CRI – 1234lm
12W 5000K THRIVE 98 CRI – 1294lm

Total length 115mm
Diameter at its widest point 50mm
Weight 175g

*LED luminous flux@85°C with no optic loses

Looks great! I’m curious if you or anyone else has done the gamut of spectrum tests ( like @Maukka does) on the bridgelux thrive? I haven’t been able to find one anywhere on the internet that haven’t been done by Bridgelux themselves.

The next generation of ceiling lights with its own assembly system is being prepared. The product will be based on Bridgelux THRIVE diodes (solarlike spectrum) in 10, 13 and 17W power options and provided by 5 years warranty.

I am also very interested in some measurements on the bridgelux CoBs.
The specs almost seem too good to be true.
Also really sad they don’t offer 18V Thrive variants.
