Sayhon SH1200 is a compact LED grow light built for 3×3 ft tents. It uses OSRAM OSCONIQ S 3030 diodes (GW QSLR31.EM) and a switchable supplemental bar providing UVA 390 nm, IR 730 nm and extra blue at 460 nm. The main board mixes 2700K and 5000K whites with deep red 660 nm to cover 400–760 nm. Average power draw is 108 W ±3%, with a listed efficacy of 2.7 µmol/J. A manufacturer PPFD map indicates about 1120 µmol/m²/s at 12 in. The fanless board includes 0–100% dimming, wide 100–277 V input, and 296 total LEDs. The aluminum panel measures 14.0 × 11.8 × 2.4 in and is positioned as a 250 W HPS replacement for small enclosures and seed-to-harvest use.
