Strobe safety

Photosensitive epilepsy is real and rare: roughly 3% of people with epilepsy have seizures triggered by flashing light or certain patterns, most commonly appearing in ages 7-19. The provocative range for flash is roughly 3-30 flashes per second, with peak sensitivity commonly cited around 15-20 Hz — squarely where club strobes live. Saturated red flash is singled out as higher-risk in broadcast and accessibility guidance; WCAG (the web accessibility standard, drawing on broadcast research) uses a three-flashes-per-second threshold as its general safety line.

What that means in the booth: strobes are a spice, not a base. Keep bursts brief and earned. Avoid sustained strobing in the most sensitive band, avoid saturated red strobe entirely, and if the venue posts strobe warnings, that's your rig they're warning about — honor it. You can hit as hard with a two-second white burst as with a two-minute assault, and only one of those is defensible.
