Giesemann Powerchrome Actinic+ - T5 High Output Lamp - 48 Inch - Package of 4

Description

A mixture of 40% Actinic and 60% Blue makes even the drabbest corals stand. Great when used with 10K or 6500K metal halide lamps to encourage bluing in SPS. 450nm peak is similar to Radium Blue metal halide lamps. Other preferred ratios include 1:1 with Midday Lamps, or 2:1:1 Midday/AquaBlue +/Actinic for best blend of bluing and fluorescence.
