PHILIPS 36W 5000K UGR<16 IP40 RG0
PHILIPS LED Blackboard Light Series SP135P
Full-spectrum high-CRI LED blackboard luminaire with one-piece pressed grille diffuser — Ra>96, R9>93, UGR<16 anti-glare, RG0 blue-light safety, IP40 sealed light chamber, 30,000 h rated lifetime. Engineered by Signify for the writing-board plane of K-12 classrooms, tutoring centers and lecture halls.
Feature Highlights
Full-Spectrum High CRI
Ra>96, R9>93 full-spectrum LED chips render chalk marks, whiteboard ink and skin tones accurately — critical for visibility at the writing-board plane.
Ultra-Low Glare UGR<16
One-piece pressed grille with through-rib reinforcement and seamless arc edge keeps glare below the EN 12464-1 classroom limit while students face the board.
Flicker-Free, RG0 Blue Light
Flicker-free operation and photobiological safety RG0 (IEC 62471) protect the developing eyes of school-age children during board-facing lessons.
IP40 Sealed Light Chamber
Sealed optical chamber keeps chalk dust and insects out of the LED cavity — maintenance-free in dusty classroom environments.
High PF > 0.95
High power factor above 0.95 delivers reliable, clean electrical quality on shared school distribution networks.
30,000 h Rated Lifetime
Rated 30,000 hours of operation — over a decade of typical K-12 school-shift service before replacement.
Application Scenarios
K-12 Writing Boards
Blackboards and whiteboards in primary and secondary classrooms. The slim 1,200 mm batten distributes light evenly across the full writing surface so board content stays legible from every desk.
Lecture Halls & Presentation Walls
Front walls of multimedia lecture halls, tutoring centers and corporate training rooms where presenter-facing illumination is required without glare into the audience.
Retrofit & New-build Projects
Pairs with SP136P grille classroom luminaires in government and school-board retrofit tenders following Chinese classroom lighting requirements (GB 50034-based design targets).
Installation & Mounting
SP135P is a Class II-style suspended luminaire for the writing-board plane. Installation must be carried out by a qualified electrician with the mains supply switched off. Mounting brackets and suspension rods are selected per project ceiling drop.
Safety Warning. Disconnect power before installation, inspection or removal. The light source is non-user-replaceable; if the LED module reaches end-of-life, replace the entire luminaire. Installation must be performed by a qualified electrician in accordance with local electrical codes.

Frequently Asked Questions
What is the difference between SP135P blackboard light and SP136P classroom light?
SP135P (12NC 911401903088) is the blackboard luminaire: a slim 1,200 × 64 × 104 mm batten that lights the writing-board plane with 3,000 lm at 85 lm/W. SP136P is the general classroom luminaire: a 1,195 × 295 mm grille panel for desk-plane illumination with 3,250–3,380 lm. Both share the same full-spectrum high-CRI 5,000 K family design with UGR<16, RG0 and IP40, and are designed to be installed together as one classroom lighting solution.
Where is SP135P installed in a classroom?
SP135P is mounted above and parallel to the writing board so the light washes down evenly across the full blackboard or whiteboard surface without glaring into students' eyes. A typical K-12 classroom pairs several SP136P classroom luminaires over the desks with one or two SP135P blackboard luminaires over the board. Installation must be done by a qualified electrician with the mains supply switched off.
Can SP135P and SP136P be ordered together as one classroom solution?
Yes. Both series ship from Honnex Lighting and are commonly ordered together for school retrofit projects. For layout assistance, quantity recommendations and project pricing, contact sales02@honnexlighting.com.
What is the rated lifetime and replacement guidance for SP135P?
SP135P is rated for 30,000 hours at Ta 25 °C. The LED light source is non-user-replaceable — at end of life, replace the whole luminaire. For warranty terms, type-test reports and bulk pricing, contact sales02@honnexlighting.com.
