Testing video. The most reviewed NICREW model out of all NICREW products (4900+ reviews 4.5 stars on amazon). PAR testing done in water for 18-24" model. This light has a wider angle light spread compared to HL-3040, ADE-400C, and SKYLED. PAR values are similar to the HL-3040 and SKYLED. The ADE-400C is still superior in PAR value and is the best bang for your buck if you want a strong light. Otherwise, low to medium tech planted aquariums will do fine with this light.
PAR tested using Seneye PAR meter unless otherwise noted in the notes section. Testing process is documented here
