Technical notes
Notes on specification and site work
Short technical notes on the decisions that decide whether a strip detail works: which construction to choose, how the run is fed, how it is sealed and how it is mounted. Written for specifiers, installers and buyers comparing options.
SK6812 vs WS2812B vs HD108: SPI and DMX512
WS2812B and SK6812 use single-wire NZR data, while HD108 is a clocked SPI part. Compare frame rate, dimming, white channel and DMX512 architecture before choosing the pixel chip.
COB or SMD: choosing the line that fits the detail
Both families are flexible strip, but they fail in different places. A practical comparison of dotting, profile depth, output and bending.

Choosing an IP rating for wet and outdoor strip
IP65, IP67 and IP68 are not interchangeable. Where water actually enters a strip, and how the body, end caps and cable entry have to be treated.

Colour temperature and CRI: specifying white light that matches
Why two 3000 K strips can look different in the same room, and how binning, CRI and dimming control the result.

Voltage drop and maximum run length, explained
Why the far end of a long run looks dimmer, how 24 V changes the calculation, and the wiring arrangements that fix it.

Wiring DMX and SPI pixel runs without flicker
The difference between DMX512 and SPI, how universes map to pixels, and the grounding and power-injection details that decide stability.

Mounting profiles: diffusion, fixing and heat
A profile is not only a cover. How channel depth, diffuser type and fixing method change the appearance and the life of the strip.
ReadA question the guides do not cover?
Send the drawing, the run length and the control method. We will answer with the strip, profile and driver that fit the detail.
