The Grand Master LED Tarantula Explorer is a commercial 10‑bar fixture purpose‑built for vertical racks, low ceilings, and 5x5 ft flowering tents. It features manual knob dimming plus RJ‑port dimming (0–10V, DIM‑TO‑OFF), a folding chassis for rapid installs, IP66 environmental sealing, LEDESTAR diodes, 6kV surge protection, and a 5‑year warranty, making it a robust choice for Australian grow rooms.

The Explorer runs two adjustable channels driven by a mixed LED configuration (9000K + 2200K + 660 nm) to fine‑tune veg‑to‑flower balance. The manual includes 12 spectrum possibilities (see SPD charts on pages 5–6) so you can match crop stage and phenotype with confidence.

Typical performance targets (manufacturer data): 2.67 umol/J overall PPE and 3,845 umol/s PPF with a 5' x 5' flowering footprint. Mount 12–18 inches above canopy to hit PPFD targets in enriched environments; note the factory baseline safety height is ≥36 inches above canopy—use a PAR meter to dial intensity for your cultivar and CO₂ strategy.

For group control, pair with the Grand Master Controller; RJ‑port pinout is specified in the manual (RJ14 6P4C).
