I was not able to personally review this light but Leticia Fang of ONF has graciously provided me the PAR data. This data applies to both Standard 24 inch (60cm) and Standard 36 inch (90cm). I've only tested the ONF Flat Nano and I already know that this company makes extremely sleek and aesthetically pleasing light fixtures. So I have high expectations of this light. One user has reviewed that the light was able to penetrate his 700 gallon 36 inch deep tank and reach the bottom. Some users have issues with the app being quirky with a learning curve. All in all, this seems like a great light for a nice rimless tank.
