LED QUANTUM TRAYS
SproutBoxx LED quantum trays are high performance LM281B LED grow lights with a unique IP67 waterproof design.
With high efficiency Samsung LM281B LEDs and our optimised full spectrum that includes Sanan UV and IR diodes, SproutBoxx YD-XK quantum trays provide excellent lm/$, emphasising the blue wavelength that stimulates growth and phytonutrients, with an industry-leading PPE supporting high maximum yields of 2.5g/W dried.
Onboard dimming and spectra controls allow custom adjustment of UV and Infra Red light to support the very best growth at every stage of development, stimulating photosynthesis, preventing disease, and making more bioactive compounds. And with a high PPE of 2.74 µmol/j at full spectrum, optimizing light for different growth stages doesn't comprimise on yield.
93% efficient Mean Well XLG LED drivers confer added cost savings from power efficiency, delivering uniformly high PPFD/PAR spreads for 4x2 coverage areas in 100W and 240W power options, with daisy-chaining straight out of the box and a unique power design that allows up to 50 powered from a single mains outlet.
Thanks to high lm/$ and top quality components, SproutBoxx YD-XK quantum trays are the best lighting for outdoor enterprises or growers seeking a high performance and versatile light, guaranteed to deliver the best results.


Ingenious Design
The YD-XK's unique design makes it ideal for outdoor use.
The splashproof hood and IP67 rating ensures water can't create damage and the specially coated reflective tray casts a 120° beam angle of uniformly high PPFD/PAR for 4x2 areas.
Up to 50 lights can be powered from a singe light's mains outlet - a tidy, straightforward solution for commercial enterpises or enthusiasts looking for year-round supplemental lighting.
