Its simple really. The white version is using dedicated white led pixels. Your version is using rgb pixels to make white and its underpowered to do so. White requires more power since it uses all 3 colors. The best woild be hex panels with RGBW leds so that it has dedicated white.
They are actually out of stock of the RGB ones so the link defaults to the white version of them. I already asked the seller when they will be back in stock and he said they will be in stock in 30 days.
Update: I ended up returning the lights since they weren’t bright enough. I bought a second set and still couldn’t light up my garage at full brightness. I’m gonna be trying out the Govee RGB recessed lights now
