Entertainment Lighting

The failure mode for venue lighting is not the fixtures. It is a system only its installer can operate, so it ends up parked on one look for a year — usually the look it was left on the night it was commissioned. That is a wasted investment, and it is entirely avoidable.

We build the show file around the way the room trades. A handful of presets that match the parts of the evening, reachable from a wall panel or a tablet, and a way back to something sane when a guest has been pressing buttons. Deeper control stays available for whoever wants it, but nobody needs it to open on a Tuesday.

Onyx is our usual control platform. It runs on a console or on a PC and the same show file moves between them, which matters when a venue starts with a laptop and later wants a fixed panel. ENTTEC handles the interfaces, nodes and pixel drivers that get DMX from the control layer out to the fixtures, and that is where most of the practical design work lives: universe planning, addressing, and knowing where a data run stops being reliable.

Addressable LED tape is the most common thing we get called in to fix. It is cheap to buy, and every part of what makes it work — power injection intervals, data run length, the driver's pixel budget, the difference between a fixture that dims smoothly and one that steps — is invisible at purchase time.

A run that is under-injected shifts colour toward its far end, usually to a dull red, and no amount of controller adjustment brings it back. A data run past its limit does not fail cleanly either; it flickers on some frames and not others, which reads as a faulty controller and gets the controller replaced. Both are design decisions made before anything is bought.

So the pixel budget and the injection plan get worked out on paper, with the driver chosen for the count rather than the count squeezed into whatever driver was ordered.

Some rooms want moving image rather than more light — a projection surface behind a stage, a mapped feature wall, content that changes with the night. Resolume is the media server we use for that. It plays and maps content, takes live input, and can be driven alongside the lighting control so the video and the lights are not two systems competing for one operator's attention.

The honest caveat is that mapped projection is a commitment. It needs throw distance, surface, ambient light control, and content somebody keeps current. Where a room cannot give it those, we will say so rather than install something that looks impressive at handover and is switched off by spring.

A large share of this work is inherited. A previous installer left, the laptop with the show file went with them, and the room has been on one scene ever since. That is recoverable more often than people expect.

We document what is actually in the room, find out what is addressable and what is not, and tell you honestly whether the sensible move is a new control layer around the existing fixtures or replacing fixtures that were never going to do what you wanted. Sometimes the answer is that the rig is fine and only the control was ever the problem.
