Apache Tech AT120WB White and Blue LED Grow Light | 8300K to 20000K Options – 1:3 White/Actinic Blue (14000K)

Apache Tech AT120WB Spectrum Options, From 8300K to 20000K The AT120WB is the blue-leaning member of Apache Tech's 120 series, and it is sold in four white-to-blue ratios. The 3:1 White/Blue version runs at 8300K, the warmest and most plant-general of the set. Next comes 50/50 White/Actinic Blue at 10000K, then 1:3 White/Actinic Blue at 14000K. The last option is 100% Actinic Blue at 20000K, with no white diodes at all. The series is rated at 1.9A per unit and 120 lumens per watt. Diodes are rated for 50,000 hours, which is years of eighteen-hour veg days. Two optics are offered, a narrow 14° lens and a wider 50° lens. The polished aluminum housing cools passively, so there is no fan to fail or to add noise. Blue-heavy light keeps internodes short and leaves broad, which is why these ratios suit mother plants and clones. The same panel also shows up over reef and planted tanks, where actinic blue drives coral color. Choosing a White and Blue LED Grow Light Ratio A white and blue led grow light is a veg tool first, so match the ratio to what the plants need to do. For mothers and vegging plants, the warmest ratio gives enough white to see true leaf color while keeping growth compact. The middle ratios push further toward blue, which helps hold stretch down on clones and seedlings under a humidity dome. Pure actinic blue is a specialty choice. It is mostly used for aquariums, not for full-cycle plant growth. None of these ratios will flower a crop well by themselves, because they lack the red that drives bloom. Growers who want one panel for flower should look at the red-and-blue AT120RB instead. Many rooms run both, with blue on the mothers and red added once plants flip. Keep the narrow lens for taller plants and the wide lens for flat trays and shelves. Place it with a PAR meter. The video below shows the panel running and helps judge spread before you hang it.
