PHILIPS Grille LED Classroom Light Series SP136P
Full-spectrum high-CRI LED classroom luminaire with one-piece pressed grille diffuser — Ra>95, R9>90, UGR<16 anti-glare, IP40 sealed light chamber, 30,000 h L80 lifetime, Class II safety. Engineered by Signify for K-12 classrooms, lecture halls, libraries and corporate training rooms.
Feature Highlights
Full-Spectrum High CRI
Ra>95, R9>90 full-spectrum LED chips render textbook colors, whiteboard content and skin tones accurately — critical for art, science and reading comprehension.
Ultra-Low Glare UGR<16
One-piece pressed grille with through-rib reinforcement and seamless arc edge — below the EN 12464-1 classroom glare limit, students do not need to shield their eyes.
Flicker-Free, RG0 Blue Light
Flicker index <0.001 and photobiological safety RG0 (IEC 62471) eliminate invisible flicker of fluorescent tubes and protect the developing lens of school-age children.
High PF 0.95, THD<15%
High power factor >0.95 and total harmonic distortion below 15 % ensure reliable, clean electrical quality on shared school distribution networks. Class II double-insulated.
IP40 Sealed Light Chamber
Sealed optical chamber keeps insects and dust out of the LED cavity — maintenance-free in dusty chalk-and-pencil classroom environments.
30,000 h L80 Lifetime
Rated 30,000 hours at L80 (Ta 25°C, 90 % RH) — over 10 years of typical K-12 school-shift operation before lumen maintenance drops below 80 %.
5000K + Ra>95 Comfort CCT
5000K cool-white with high color rendering matches Chinese curriculum preferences for daytime alertness while keeping skin tones natural.
≤8 W/m² Power Density
Holds classroom power density below 8 W/m² while delivering maintained illuminance >500 lux and uniformity >0.75 — meets GB 50034 and EN 12464-1.
Application Scenarios
K-12 Classrooms
Primary and secondary classrooms in public schools, private schools and tutoring centers. The 1195×295 mm body mounts cleanly above desks with the recommended 1.7 m light-surface-to-desk drop. UGR<16 keeps students comfortable during long lessons.
Lecture Halls & Training Rooms
Multimedia lecture halls, e-reading rooms and corporate training rooms with projector screens and cameras. Flicker index <0.001 eliminates banding on recorded video and projected content.
Libraries, Reading & Computer Rooms
School libraries, reading rooms and computer laboratories where stable, low-glare illumination is required for sustained reading and screen work. RG0 blue-light classification protects young eyes.
Installation & Mounting Guide
SP136P is a Class II IP40 suspended luminaire. Installation must be carried out by a qualified electrician with the mains supply switched off. Suspension rods are not included — order separately based on your ceiling drop.
STEP 01
Fix Ceiling Brackets
Mark suspension positions (~650 mm rod spacing) on the ceiling, drill locating holes and bolt the fixing brackets firmly to the ceiling structure.
STEP 02
Thread Rods & Cable
Pass the mains supply cable through the ceiling-cap centre hole. Screw the suspension rods into the threaded seats of the ceiling cap and pre-tighten with the hex nuts.
STEP 03
Mount the Luminaire
Align the mounting ears on the rear of the SP136P body with the rod ends, push into place and secure the fixing clips on both sides.
STEP 04
Wire & Level
With mains off, connect L / N / PE to the driver terminals (see label). Power up, adjust the body to hang perfectly level, then fully tighten all hex nuts to lock the assembly.

Frequently Asked Questions
What is the difference between SP136P LED32S PSU CL and SP136P LED32S PSU CL UO?
Both are 36 W SP136P grille classroom luminaires at 5000 K, Ra>95, UGR<16 and IP40. The CL version (12NC 911401903089) is the standard non-up-light model with a sealed bottom-only light chamber and delivers 3,250 lm at 88 lm/W. The CL UO version (12NC 911401903090) adds a punched top aperture with raised-point up-light LEDs, raising output to 3,380 lm at 94 lm/W. Choose CL for general classrooms; choose CL UO when ceiling uplighting is desired to soften contrast and brighten the ceiling plane.
What classroom illuminance and uniformity does SP136P achieve on the desk plane?
Per the official specification, SP136P maintains an average maintained desk illuminance greater than 500 lux and a uniformity (U0) greater than 0.75 when installed in a typical K-12 classroom with a recommended 1.7 m light-surface-to-desk height. Power density is held to ≤ 8 W/m². These values meet China's GB 50034 and EN 12464-1 classroom lighting requirements.
Does SP136P meet China's CCC classroom lighting standard and GB 50034 photometric requirements?
Yes. SP136P holds CCC certification. Photobiological safety is rated RG0 — the highest classification under IEC/TR 62778 / IEC 62471. Color rendering Ra>95 with R9>90 keeps textbook colors and skin tones accurate; UGR<16 stays below the EN 12464-1 classroom glare limit. Combined with maintained illuminance >500 lux, uniformity >0.75 and flicker index <0.001, SP136P satisfies both EN 12464-1 teaching-space targets and Chinese GB 50034 classroom lighting requirements.
Are suspension rods included in the SP136P carton? Which rod should I order?
No — the SP136P luminaire is supplied as body only; suspension rods are NOT included and must be ordered separately. Three official accessories are available: (1) SLZ ROD L 1000 (12NC 911401903155) — 1,000 mm aluminum fixed rod, 2 pcs/set; (2) SLZ ADJ ROD L 1000 (12NC 911401903153) — adjustable 0.5–1.0 m rod, white, 2 pcs/set; (3) SLZ ADJ ROD L 1500 (12NC 911401903154) — adjustable 0.75–1.5 m rod, white, 2 pcs/set. Pick the fixed or adjustable model based on your ceiling drop and required leveling range. For bulk orders and project pricing, contact sales02@honnexlighting.com.
What is the warranty, rated lifetime, and recommended replacement interval for SP136P?
SP136P is rated for 30,000 hours at L80 (Ta 25 °C) — meaning lumen maintenance ≥ 80 % at end of life. Service life exceeds 10 years in a typical 8-hour-per-day school shift. The light source is non-replaceable; the external driver is replaceable. For replacement planning, budget for luminaire change-out at the 30,000-hour mark, or approximately every 10 years under normal K-12 operating hours. For warranty terms, type-test reports and bulk pricing, contact sales02@honnexlighting.com.
