Same tradeoff, weighted toward lamp life: ~4x life for ~30% less light,
with 95% noted as the fallback if it reads too dim in practice.

min_brightness was one line with no procedure. Setting it to 1 is wrong —
triacs stop latching reliably at very low phase angles, so it presents as
flicker rather than a dim glow. Document walking it down to instability
and backing off a step, since the usable floor is fixture-specific.
Also add max_brightness, which matters more: filament life goes roughly
as V^-13 against light as V^3.4, so running at 95% roughly doubles lamp
life for ~15% less output. Worth having on a fixture whose lamp type may
be discontinued.

Drives an old ~250 W filament stage fixture from HA via the existing
Zigbee2MQTT backbone: a 400 W-rated dimmer module wired inline into a
Schuko extension lead, ~€25.
Leads with verifying the lamp, because the wattage decides between a €25
module and a €100 dimmer pack, and it's the one step here with real fire
risk. Documents the three stop conditions (discharge lamp, transformer,
cooling fan) and the escape hatch if the lamp turns out over 400 W.
Guidance only, matching the network-integration.md convention — nothing
in this repo touches the fixture or the pairing. The Z2M side needs no
config beyond permit-join, since setup-container-host.sh already sets
homeassistant: true, and pairings live in database.db, which the restic
backups cover.
