Testing video. PAR testing done in water for the 18-24 inch model. Slightly weaker in PAR ratings to the NICREW HL-3040. This light would work great for low light planted tank set up. If you are looking for a stronger NICREW Light around the same price, check out NICREW ADE-400C. This light has 2 modes. First mode: All lights on and second mode: moonlights only. Very affordable and budget light for starting a planted tank.
PAR tested using Seneye PAR meter unless otherwise noted in the notes section. Testing process is documented here
