iTrader Positive Rating: 100% | Re: PAR data collection PAR DATA COLLECTION Aquarium size: Standard 55g Type of light fixture AND reflector: DIY hood w/ Pigtail CFLs, white semi-gloss paint interior Number of lamps, bulbs, or tubes, and wattage: 7x 13w 6500k CFLs Age of lamps, bulbs, or tubes: 5 months Other information: CFLs are mounted horizontally Distance from light fixture to substrate: 24" PAR VALUES MEASURED AT SUBSTRATE: 54 Comments: I thought I had too much light, tank is very bright. Till I learned that I'm only at 54PAR at the substrate. Going to upgrade to 23w bulbs instead of 13w and re-measure. Also I have white semi-gloss paint inside my fixture maybe aluminum reflectors is superior, will experiment with that as well. This is a high-tech tank with CO2 and ferts. Aiming for 80+ PAR |
