An ILDA laser projector uses the analog ILDA connection—a DB-25 port—to carry X/Y and RGB modulation from controllers such as Pangolin FB3. For short runs and simple rigs, an ILDA laser is often the best price path to clean aerials. This guide explains how ILDA works, where it struggles, when to go FB4/network laser, and how we deploy both in real Starshinelights projects—plus a wiring checklist, buyer advice, and a ready-to-use CTA to get a quote or bundle.

What Is an ILDA Laser Projector?
An RGB projector that accepts analog control via DB-25 (commonly called the ILDA port). Each pin carries a specific axis or color channel (X, Y, R, G, B, etc.). You connect a controller like Pangolin FB3 to ILDA IN and the projector draws the frame in real time.
Why “ILDA”? ILDA stands for International Laser Display Association. The connector is technically DB-25, but the industry uses “ILDA” as shorthand for the analog pinout ILDA documented and popularized.
ILDA vs FB4/Network (Art-Net/sACN): Which Fits Your Show?
TL;DR: Single projector + short runs → ILDA wins on price. Multi-projector independence or long runs → go FB4/network.
When ILDA shines: ≤100–150 ft (≤30–45 m) cable runs, 1–2 projectors showing the same content, tight budgets, simple installs in bars, weddings, and pop-ups.
When network wins: multiple independent heads across a venue, long distances where Cat5e/Cat6 is lighter and cheaper, and time-coded shows needing remote configuration and logging.

Real-World ILDA Limitations (and Workarounds)
Cable length & signal quality: treat ~150 ft / 45 m as a practical maximum for DB-25. Route away from power and dimmer racks; cross at 90°. If you see soft corners, shorten the run and reduce scan angle.
Independence: one DAC output = one unique stream. Daisy-chain mirrors content. For independent looks, add outputs or move to FB4/network.
Sourcing spares: DB-25 isn’t sold everywhere. Keep spares in stock; order wholesale packs for touring.
Quick ILDA Setup Checklist
Minimum kit: Pangolin FB3 (USB) or similar DAC, 2× DB-25 male-to-male (one spare), e-stop & interlocks, RCD/GFCI power, stable USB cable, and water-based haze.
Bring-up (10 minutes): bench test at 30 kpps @ ~8° → route ILDA away from power → verify e-stop and beam zones → focus small → widen until geometry stays crisp → log scan speed and color gains.
ILDA Cable, Spares & Sourcing (Price / Buy / Bundle)
Use shielded DB-25; avoid tight bends; label both ends (e.g., FOH-ILDA-01). Ask for a bundle deal (FB3 + 2× DB-25 + e-stop) to lower price and simplify buy decisions. Integrators can request wholesale and OEM/ODM faceplates. See Cables & DB-25 accessories.
Scan Speed vs. Scan Angle—How to Get Clean Text
Start at 30 kpps @ ~8° for logos/text. If lines look soft: shorten DB-25, narrow angle, reduce point count. With FB4 network lasers across large angles, Cat6 makes longer runs easier.
Safety & Compliance (Copy-Paste Checklist)
E-stop & interlocks present · audience no-scan verified · RCD/GFCI on power · lens caps on during focus · haze type confirmed · log site plan / scan settings / operator / timecode. Browse Safety interlocks & e-stop kits.
Troubleshooting Decision Tree
Soft corners / fuzzy text → shorten DB-25 → narrow angle → check test frames.
Random flicker → re-seat DB-25 → re-route away from power → swap to spare cable.
Colors off → analog gains (R/G/B) → projector test pattern → content color balance.
Need independence → add FB3 outputs or migrate to FB4/network.
Starshinelights Field Cases
Canal winter trail, Netherlands: Network backbone over long docks; kept two local ILDA units for fast focusing. Result: stable looks in rain, quick changeovers.
Rooftop bar, Guangzhou: Two 2–3 W RGB ILDA lasers within 10 m; strict price target; playlist operation by staff. Result: zero show-night complexity.
Villa façade & pool, Athens: FB4/network for independent zones; ILDA spare at FOH. Result: flexible programming; spare saved rehearsal after a switch failure.
Cost & Timeline Scenarios (By Venue Type)
Small bars/pop-ups (≤15 m): ILDA + FB3, request a bundle price, keep spares in stock.
Weddings/mid venues (≤25 m): ILDA for mirrored looks; choose FB4 if you need independent cues.
Clubs/festivals: network backbone; keep one ILDA unit as service spare. For integrators, ask for wholesale / OEM/ODM kits with labeled looms and cases.

TL;DR for Buyers
If your show uses one stream and short runs, an ILDA laser projector keeps price low and setup simple—just add a bundle so you’re always in stock. If you need multi-projector independence or long cable runs, choose FB4 network lasers and ask for a quote on a Cat6 backbone. Integrators: wholesale / OEM/ODM available.
FAQ
What is the “best” ILDA laser projector for a small bar?
Look for 1–2 W RGB, 30–35 kpps, analog modulation; keep DB-25 under 20 m. Ask for a bundle with FB3, two ILDA cables, and an e-stop.
ILDA vs FB4—how do I choose for two independent looks?
Go FB4/network. ILDA mirrors well, but independence needs multiple DAC outputs; network is cleaner over distance.
How far can I run an ILDA (DB-25) cable?
Treat 150 ft / 45 m as the ceiling. Past that, expect softness/noise; switch to FB4/network or move the controller closer.
Do I still need DMX with an ILDA projector?
Often yes. DMX is handy for shutter, dim, and effect toggles; ILDA drives the graphics. See DMX laser lights for DJs.
Can Starshinelights help with safety and approvals?
Yes—send room photos and throws. We’ll mark aperture heights, no-scan zones, interlocks, and RCD/GFCI, and suggest IP65 outdoor lasers if needed.
