DMON B420F 420W Outdoor Waterproof Beam Moving Head Light
The Dmon B420F is a professional IP55-rated outdoor waterproof beam moving head light powered by the OSRAM SIRIUS HRI 420W, delivering a razor-sharp 1.2° beam that holds up in exposed outdoor conditions without a rain cover. Built for outdoor stages, landmark light shows, and permanent outdoor installations where weather resistance is non-negotiable.
- IP55 rated — true outdoor waterproof protection, no rain cover required
- OSRAM SIRIUS HRI 420W — high-intensity, narrow 1.2° beam for long-throw visibility
- Dual stackable prisms — 8-facet + triple 8-facet honeycomb for layered beam effects
- DMX512 + RDM bi-directional control — real-time monitoring and remote firmware updates
We offer comprehensive after-sales services, including installation guidance and technical support. Our products also come with a specified warranty period to ensure a worry-free experience for our customers.
Function Description
Most beam moving heads are IP20 — fine for indoor rigs, but they need a rain cover or a roof the moment a show moves outdoors. The B420F is built IP55 from the ground up, so it can sit in an exposed outdoor rig through wind and rain without extra weatherproofing or downtime.
RDM support means your crew doesn't have to climb a truss to check a fixture's status. With bi-directional DMX512/RDM control, you can read lamp hours, monitor fixture status, and push firmware updates remotely — useful for permanent outdoor installations where physical access is limited or costly.

Frequently Asked Questions
Is the B420F truly rated for outdoor use?
Yes. Unlike our indoor beam fixtures that require an optional rain cover, the B420F is IP55-rated from the factory, built for direct exposure to rain and outdoor conditions without additional weatherproofing.
Can the B420F be controlled by third-party lighting consoles?
Yes. It runs on standard DMX512 protocol with 16 channels and supports bi-directional RDM, compatible with any DMX/RDM-compliant console on the market.
Is the lamp field-replaceable?
Yes. The OSRAM SIRIUS HRI 420W lamp can be replaced on-site without returning the fixture. Replacement lamps are available from DMON at cost price under our after-sales policy.
What does RDM support let me do?
RDM enables bi-directional communication over the DMX line — you can remotely check lamp hours, fixture status, and DMX values, and push firmware updates without physically accessing the fixture.
Do you offer OEM/ODM or custom branding?
Yes. We support OEM/ODM services including custom logo, packaging, and configuration for bulk orders. Contact us for MOQ details.
What's the warranty and how does after-sales support work?
2-year warranty with 3-business-day response commitment. Parts are supplied at cost price, and we guarantee parts availability for 5 years after any model is discontinued.
