- DR BRUCE BUGBEE: Apogee DLI PAR meters have been designed and refined by Dr. Bruce Bugbee, a world-famous crop physiologist
- DLI-500 FULL-SPECTRUM METER: Provides research-grade measurements of PAR (PPFD), DLI, and photoperiod from 400-700 nm for all plant grow-lighting.

Monitoring and adjusting the DLI (total photosynthetic photons in a 24-hour period) and photoperiod (hours of light) are crucial for optimizing plant health, flowering, and other morphology effects. PPFD, DLI, and photoperiod data can be viewed onscreen or downloaded via USB-C for analysis.
