Driver ICs & Protocols
Which addressable driver IC to specify — WS2811, WS2812B, WS2815, SK6812, TM1814, UCS1903 — and how Art-Net, DMX512 and SPI change what you can build.
Engineering guides for addressable pixel LED
Driver ICs and protocols, IP ratings, wiring and voltage drop, certification and export — written by the engineers who build the product, for the people who have to specify it.
11 topics, each mapped to a real sourcing decision
IP Ratings & Waterproofing
What IP20 through IP68 actually survive outdoors, how sealing is really done, and what evidence a lighting handover needs.
Pixel Strip Selection
Choosing pixel LED strip for a real job: RGB vs RGBW vs RGBIC, voltage drop over long runs, binning and colour consistency.
Stage & Touring
Pixel fixtures that survive touring: rig-and-strike durability, bars vs tubes, wireless DMX, and what to check before a show.
Facade & Curtain Wall
Specifying facade and curtain-wall lighting: IP class, pixel pitch, power injection layout, and the handover evidence clients ask for.
Mining & Tunnel (AC36V)
AC36V mains lighting for mines and tunnels: what underground fixtures must survive, cut-to-length runs, and the certifications to check before buying.
OEM, ODM & Distribution
For distributors and private-label buyers: MOQ, tiered pricing, sample policy, what a Chinese pixel LED factory can actually customise, and how to vet one.
Certification & Compliance
CE, RoHS, EMC, IP66 and BIS explained for LED lighting export — how to verify a certificate number and what a compliance team should ask for.
Project Case Studies
Real deliveries with real numbers: 86,500 pixel points on a Singapore observation wheel, 10,000 m of AC36V strip in a South African mine, and more.
Accessories & Add-ons
Buyer guides for what goes around the fixture — power supplies, aluminium profiles, connectors and wiring — so a pixel install actually works.
Signage & Storefront
Neon flex or pixel strip for signage, bending radius, cutting and sealing on site, and keeping colour consistent across a multi-store rollout.

Facade Lighting Handover: Proof, Not Paperwork
A facade lighting handover is an evidence pack, not a folder: how to test measured lux, batch color match, IP joints, the DMX universe map and spares.
What RoHS Means for LED Controllers
RoHS on an LED controller is decided by the materials inside the box, not the label: what the directive covers, which documents prove it, and a 7-step check.
Club Lighting: Bars, Tubes & Pixel Points
Club lighting is an environment, not a rig: bars, tubes and point lights each own a zone. Map the room by what guests see, then size control, power and heat.
LED Strip Operating Temperature: Ta, Tc or Tj?
Most LED strip datasheets quote a single operating temperature without saying which node it measures. Here is how to read Ta, Tc and Tj and compare fairly.
LED Strip Light Flickering: Pixel-System Fixes
Most flickering-strip advice stops at the power supply. On addressable pixel systems, read the pattern first: power, data or refresh rate decides the fix.
SPI vs PWM vs DMX: How Pixel LEDs Are Driven
SPI vs PWM is not a real choice: PWM sets brightness inside each pixel, SPI carries the data, DMX handles addressing. Here is which layer decides your project.

Zoning decides where a pixel installation fails. How to split a run into protected power zones, size each feed, and document them for the next technician.
Mining LED Certifications: Buyer's Checklist
Read Ex markings, match ATEX, IECEx, MSHA or GB 3836 to your site, and check the IP test report, model scope and voltage rule before you order mining LEDs.

Art-Net Controller for LED: Verify in 6 Checks
MADRIX compatible on a datasheet proves little. Six checks — protocol version, port addressing, universe budget, SPI chip set, refresh, failover — settle it.
