Overview
Starting out with a 2×2ft tent does not mean settling for weak light. The RX-G80 240W is the smallest folding grow light in the G80 family, sized for 2×2ft entry-level tents, and Koray’s secondary optics lift its average PPFD by about 50% over a typical 200W quantum board. All figures below come from Koray’s official G80-240W spec sheet (factory-measured, tolerance ±10%).

+50% Average PPFD vs 200W Quantum Boards
Measured against a typical 200W LED quantum board, Koray’s secondary optics deliver about 50% higher average PPFD across the 2×2ft footprint — the entry-level grower gets real penetration through the canopy instead of a dim top layer. Efficiency is 2.9 µmol/J for the complete lamp (not just the LED package), per the spec sheet.
Spectra and LEDs
Samsung LEDs with 660nm deep red power the G19 / G26 spectra, both proven over years of medicinal-plant cultivation. The G80 folding design ships flat, folds open in seconds, and takes up minimal space in a 2×2ft tent.
Installation
Hang the light from the four corner cables with carabiners at the 2×2ft tent top, light facing down; working height is about 0.4–0.6 m, matching the 1200 µmol/m²/s operating point at 0.46 m.
Applications
- 2×2ft entry-level and hobby grow tents
- Small-batch cultivation and seedlings
- First-time growers moving up from quantum boards
