1. Brightness: how many watts / lumens do you need?
Wattage is only a rough proxy; lens quality, gobo transmission and image size matter as much. As a rule of thumb:
- Dim interior / lobby: 15–50W (about 1,800–5,500 lm) is plenty.
- Lit storefront or semi-outdoor: 80–150W (about 8,000–11,000 lm).
- Bright building facade / long throw (10–30 m): 200–600W, chosen after an on-site projection check.
2. Weatherproofing (IP rating)
Indoor-only units need no IP rating. For outdoor, storefront or event use, choose IP65 or IP67. IP67 tolerates rain, dust and temperature swings for year-round installation. Always seal the cable entry with the included waterproof gland.
- IP65: protected against water jets; fine for sheltered outdoor spots.
- IP67: immersion-proof to 1 m; the safer choice for exposed facades and ground-level units.
3. Custom gobo — can it show YOUR logo?
This is the whole point of a gobo projector. Confirm the supplier engraves your artwork (vector AI/CDR/PDF or hi-res PNG). At Jingyu we engrave custom glass gobos in 2–3 days, MOQ 1 piece — sharper and more durable than metal gobos under high power. Send your logo and we return a proof before production.
4. Throw distance & image size
As the projected image grows, brightness per unit area drops. A 100W unit may give a crisp 2 m logo at 10 m but a weak 6 m logo from the same spot. Before ordering, measure the mount-to-surface distance and the required logo diameter.
- Mounting height and angle (keystone / zoom if available).
- Surface colour: dark walls read brighter than white, which scatters light.
- Ambient light already falling on the surface — this decides the wattage, not the distance alone.
5. Control & patterns
Pick the control features your use case needs:
- Fixed vs rotating: rotation adds motion for events and venues.
- Multi-image: some units switch 4 / 7 / 8 patterns by remote — ideal for rotating promotions.
- Remote: on/off plus mode switching from across the room.
6. Certifications & power adapter
For export, look for CE, RoHS, FCC and ISO9001 (UL/CSA on request for North America). Every Jingyu unit ships with the correct voltage and plug adapter for the destination — US/UK/EU/AU/RU/UAE/BR/NZ — so it works on arrival.
