Open-Air Electronic Festival — Three Stages, Twelve Days
Germany’s summer festival season does not wait for good weather. The promoter wanted a main-stage rig that could stay rigged and powered through twelve days of rain instead of being bagged and struck every night — without doubling the generator budget.
The brief
- Weather exposure. Nine of the twelve show days had rain. Every fixture on the three exposed trusses had to run uncovered, unattended, overnight.
- Load-in window. The site gave 36 hours to rig three stages. Conventional bagging and de-rigging each night was not an option.
- Power budget. Two 125 A generators fed the whole site. The rig had to be re-specified around a hard 60 kW ceiling per stage.
- Fault visibility. With 168 fixtures spread over 200 m of field, the crew needed to find a dead unit from FOH instead of walking the site.
What we delivered
- IP65 where it matters. SL-IP-B400, SL-IP-W400 and SL-IP-H600 bodies with sealed optics and conformal-coated drivers on all exposed positions; standard bodies only under the stage roof.
- Generator load model. We delivered a per-position current draw table so the site electrician could balance phases before load-in, not during it.
- RDM monitoring. Two SL-C2 controllers distributed Art-Net and polled every fixture — fixture status, temperature and hours visible from FOH.
- Pre-rigged trusses. Fixtures shipped clamped and cabled on pre-built truss sections in flight cases, cutting the rig time per stage to about 12 hours.

“We stopped budgeting for weather. The rig went up in June and came down in June — nothing was bagged, nothing was swapped, and we came in under generator cost for the first time in four years.”— Technical Director, festival production company, Hamburg
