I recently took some PAR readings of the Nicrew HyperReef 50W (Generation 1) light. My tank is 15 inches tall, and the light is mounted using the standard bracket that comes with it, placing the fixture about 23 inches above the sand bed.
The readings were taken using a Danoplus PAR meter, so take the numbers with a grain of salt. That said, the Danoplus readings should be fairly close to those from an Apogee PAR meter if your unit has the new factory calibration—which applies to devices purchased after August 1, 2025. ***According to the linked youtube video pinned comment***
Initially, I ran the light at 70% blue and 5% white, and while I did see some coral growth, the colors and growth rate noticeably improved when I increased the settings to 100% blue and 25% white. I’m currently experimenting with pushing the intensity a bit higher to see if I can get even better results.
