What the GK Series High Bay is for
A three-size die-cast aluminium high bay — 100W, 150W and 200W — with an integrated wide-input driver and a spectrum built to order. Where the linear and panel fixtures are engineered around a fixed bench, the GK is engineered around a ceiling: hang it high, cover a wide circle, and specify the diode mix for the crop rather than accept a catalogue spectrum.
What you get
- Three sizes on one platform: GK100 (Ø290 × 160mm, 140 diodes), GK150 (Ø310 × 165mm, 210 diodes), GK200 (Ø400 × 165mm, 280 diodes).
- Spectrum built to order — diode mix specified per crop rather than fixed at the factory.
- Wide-input integrated driver: AC 100-364V, 50/60Hz, matched to each wattage.
- Die-cast aluminium housing, polished and stove-varnished with a frosted texture; transparent cover.
- Light net weights — 2.14kg, 2.73kg and 3.44kg — so ceiling fixing is rarely the constraint in a retrofit.
- Two per carton, packed 340 × 340 × 145mm (GK100) through 410 × 410 × 155mm (GK200).

Before you spec it
What is the GK actually for?
High-ceiling spaces where a bench-shaped footprint does not apply: greenhouse gutters, tall propagation halls, warehouse-conversion rooms before the racking goes in, and mixed horticultural/industrial buildings. In a fixed-bench flower room a panel fixture with a published PPFD map will give you better uniformity over the bench, and a photometric file to plan against.
GK or GM?
What does "customised spectrum" mean in practice?
Tell us the crop and the stage — leafy greens under supplemental light, propagation, ornamentals, cannabis mothers — and the factory builds the diode mix to suit. It is why this range has no single published spectrum graph.
Why is there no PPF figure on this page?
Because the spectrum is built per order, and PPF depends on it. We publish the mechanical and electrical specification, which is fixed, and quote photometrics with the build.
