Restart, il punto di quell'articolo , che non parla di luci LED, per me però è altro.. nell'esperimento le luci prese come test sono :
Above one tank was placed a 20K 175W XM single-ended metal halide bulb; a second tank was illuminated with a 10K 175W XM single-ended metal halide bulb, and the third tank was topped with a Tek Light fixture featuring 4 x 24W T5 bulbs (2 x 24W Aquasun VHO's in the exterior positions, 1 JALLI 10000K, and 1 AB actinic blue in the interior positions).
Quindi niente LED ..
Per me uno dei punti più interessanti è questo :
More recently, Schlacher et al. examined growth rates of Acropora solitaryensis under 150W metal halide bulbs rated at 5.5K, 10K, 14K, and 20K color temperatures (Schlacher, 2007). After 3 months of grow-out, the overall growth rates under the different bulbs were quite distinct: 6.2 mg/day at 5.5K, 4.9 mg/day at 10K, 8.5 mg/day at 14K, and 10.9 mg/day at 20K.
