5000 K renders a crisp, daylight-like tone that many schools prefer because it supports alertness during morning and afternoon lessons and makes whiteboard content appear cleaner. Photometric quality is identical to the 4000 K version — UGR < 19 (≤ 16 in classroom mock-up), Ra > 95, R9 > 90 and flicker metrics PST < 1, SVM < 0.4, modulation depth < 0.2% — so the choice is purely about the color tone your curriculum or local specification prefers.

Per the official packing list, each SP130S carton contains: 1 × luminaire body, 2 × ceiling mounting plates, 2 × mounting ear brackets, 5 × expansion bolts (φ8 × 40 mm), 6 × M5 hex nuts, 2 × M5 × 12 mm hex bolts and 1 × user manual. Suspension rods are NOT included — for dropped mounting please order rods separately (recommended spec: φ12.7 mm tube, M12 × 1.25 mm thread, 14 mm threaded length).

Rated lifetime is 50,000 h @ L70B50 @ Ta 25°C with > 25,000 switching cycles, matching typical 10-year school renovation cycles. The external driver is replaceable without removing the luminaire from the suspension rods, and the IP40 housing keeps dust and insects out of the optical chamber. The light source itself is non-user-replaceable.
