I am currently testing the LED of the Brinyte ZT40.
I am pretty sure that this is NOT the Luminus SFT-25R in a 5050 package.
The LES is bigger as for SFT-25R (different LED chip is very likely used, this unknown emitter has 1.8 mm diameter LES, the SFT-25R only 1.7mm), the pattern of the bonding wires is different. Another thing that stands out: the LED chip is embedded too deeply in the frame. Light emitted from the side is reflected back from the silver frame, which reduces the luminance. The SFT-25R has not done this.
More to this in the next days.
