SurgeFX SF-BM100 LED Beam Moving Head Light

What the BM100 Does

The SF-BM100 is a beam moving head — a fixture designed to produce tight, concentrated shafts of light visible mid-air when haze or fog is present, and to project colored gobo patterns onto surfaces. The 100W white LED fires through a precise optical system: color wheel → gobo wheel → 8-facet prism → output lens — producing a 3.6° beam that stays tight and punchy across long throw distances. This is a dedicated beam fixture. Not a wash. Not a spot/beam hybrid. A beam.

What's Inside

The 3.6° Difference

Beam angle defines how tight or wide a light's output is. Most wash fixtures operate at 15°–60°. Most spot fixtures sit around 10°–20°. The BM100 operates at 3.6° — an ultra-narrow beam that concentrates all 100 watts of output into a shaft barely wider than a flashlight at close range. This does two things: it makes the beam extremely visible mid-air through haze (the tighter the beam, the sharper the shaft looks), and it allows the fixture to project patterns at much longer distances without the image washing out. A 3.6° beam at 50 feet still looks like a tight, defined shaft — a wider beam would have spread and lost intensity long before that.

Who It's For

The BM100 is built for anyone who wants professional-grade beam effects without the premium price tag. Mobile DJs who've outgrown basic mini beams and want prism fan effects and tighter, punchier beams. Clubs, bars, and lounges that want dramatic aerial effects cutting through their haze systems. Event professionals running weddings, galas, and corporate events who need beams that read at a distance. Houses of worship that want sharp gobo projection and atmospheric beam effects for services and productions. And anyone building a multi-fixture rig who wants the beam layer to have real impact.

The 8-Facet Prism — How It Works

A prism sits in the optical path between the gobo wheel and the output lens. When engaged, it refracts the single beam into multiple copies. The BM100's 8-facet prism splits one beam into eight — creating a fan of beams radiating outward from a single fixture. The prism rotates bi-directionally at variable speed: slow rotation creates a mesmerizing spinning fan effect, fast rotation blurs the individual beams into a whirling cone of light, and static positioning locks the fan at any angle.

What the Prism Changes

The prism is independently controllable via DMX — you can engage or disengage it at any point during a show, switch between single-beam precision and multi-beam drama in an instant. Slow pan sweep with prism off → snap prism on at the drop → eight beams explode across the room. That's the kind of dynamic range the prism provides.

Optical Pipeline — From LED to Output

Understanding the optical path helps you visualize how effects combine:

100W White LED → Color Wheel → Gobo Wheel → 8-Facet Prism → Focus Lens → 3.6° Output

Each element is independent. Any combination is possible: colored beam with no gobo and no prism (clean colored shaft), gobo pattern with no color filter (white pattern projection), gobo + color + prism (eight copies of a colored pattern), rainbow spin + prism (multi-beam rainbow fan), and everything in between.

Where It Fits in the Lineup

The BM100 occupies the critical middle ground: the first fixture in the lineup with a prism at less than half the price of the next step up. For buyers who want beam + gobo + prism effects without the investment of a spot or BSW hybrid, the BM100 delivers the core visual impact.

Applications

• Mobile DJ — Prism beam fans across the dance floor. Sound-active mode reacts to bass. Gobos project patterns on walls. The 3.6° beam cuts through venue haze for dramatic mid-air shafts. T-bar or truss mountable at 9.92 lbs.
• Clubs & Bars — Tight beams and prismatic fans create the dynamic aerial look that defines club lighting. Run 4–8 on DMX for full room coverage. The ultra-narrow beam stays defined even in heavily hazed environments.
• Weddings & Events — Gobo projection for textured lighting on walls and ceilings. Clean colored beams for dramatic reveals and first dance moments. Prism fans for reception party energy. Elegant at low output, high-energy when needed.
• Houses of Worship — Sharp gobo projection for visual texture during services. Atmospheric beams through light haze for worship moments. CRI 85 for camera-friendly output during livestreams.
• Multi-Fixture Arrays — At $249 each, building a 4-unit beam array ($996) or 6-unit array ($1,494) is financially realistic. Master/slave sync keeps all units coordinated without a controller. Multiple BM100s with prism engaged = a wall of spinning beam fans.

DMX-512 Control — Dual Channel Modes

The SF-BM100 connects via standard 3-pin XLR (in/out for daisy-chaining). Set the DMX start address and channel mode from the onboard LCD display with navigation buttons. Two modes available:

Extended Mode Channel Functions

DMX Universe Planning

In extended mode (13 channels): 39 BM100 fixtures per DMX universe (39 × 13 = 507). In basic mode (11 channels): 46 fixtures per universe (46 × 11 = 506). Mixing fixture types on the same universe works well — for example, 8× BM100 at 13CH (104 addresses) + 8× MW710 wash at 14CH (112 addresses) = 216 addresses total, well within a single 512-channel universe.

Frequently Asked Questions

What's the difference between the BM100 and the BM60?

Both are beam moving heads with color wheels and gobo wheels. The BM100 ($249) upgrades in every dimension: 100W LED vs 60W (67% more power), 9 gobos vs 7, 3.6° beam angle (tighter, punchier), and — the biggest difference — an 8-facet rotating prism that the BM60 doesn't have at all. The prism multiplies your beam into eight, creating fan effects and starburst patterns that fundamentally change what the fixture can do. If your budget allows the extra $50, the BM100 is the better investment for beam effects.

What about the BM100 vs the SP90?

Different tools. The SF-SP90 ($489) is a gobo spot — dual gobo wheels (7 static + 6 rotating), 3-facet prism, electronic focus, CRI 95, 18 DMX channels. The SP90 excels at precise gobo projection with rotating gobos that spin independently. The BM100 ($249) is a dedicated beam — single gobo wheel (9 fixed), 8-facet prism, manual focus, tighter 3.6° beam for mid-air shaft effects. If your priority is projected patterns with maximum flexibility, SP90. If your priority is punchy beams and prism fans through haze, BM100. Many rigs use both — SP90 for gobo detail, BM100 for beam impact.

Do I need haze to use the BM100?

You don't need haze, but the BM100 is designed to shine with it. Without haze, you'll see gobo patterns projected on surfaces and colored beams hitting walls — still useful and visually interesting. With haze, the 3.6° beam becomes a visible shaft of light in mid-air, and the 8-facet prism creates eight visible shafts fanning outward. The difference is dramatic. For beam fixtures, haze is the single biggest visual upgrade you can add. A SurgeFX Haze FX at low output provides the perfect atmospheric density.

Do I need a DMX controller?

No. Sound-active mode (reacts to music), auto-run (built-in programs), and master/slave (sync multiple units) all work without a controller. The BM100 works out of the box with just a power cable. DMX gives you precise control over every function — color, gobo, prism, movement, timing — but it's not required.

How many can I run on one power circuit?

Each unit draws approximately 120W at full output. On a 15A/120V circuit (1,800W available): up to 14 fixtures with headroom (14 × 120W = 1,680W). On a 20A circuit (2,400W): up to 19 fixtures. The BM100's moderate power draw makes multi-fixture arrays practical on standard venue wiring.

Is it outdoor rated?

No. IP33 is an indoor rating. Not waterproof. Use indoors or under fully covered/tented outdoor stages only.

What's the 180° tilt mean in practice?

The BM100 tilts 180° (straight up to straight down through the front arc). This covers the standard performance range — aiming at the audience, the stage, and the ceiling. Some fixtures offer 270° tilt which adds rear coverage. For most applications (DJ setups, club installs, event lighting), 180° covers every angle you'll typically need. The 540° pan provides full horizontal rotation with 1.5 complete turns.

Can I use the prism with gobos at the same time?

Yes. Every element in the optical path is independent. You can run gobo + color + prism simultaneously — the result is eight copies of a colored gobo pattern fanning outward from the fixture. This is the BM100's most visually complex mode and it's spectacular through haze.

How loud is the fan?

The BM100 uses fan cooling with thermostat management. At 100W, it generates more heat than the 60W BM60 and requires more active cooling. Fan noise is moderate and typical for this fixture class — inaudible over music and event ambient sound. In quiet settings (theater, small worship services), the fan may be faintly perceptible at close range. Position at a reasonable distance to minimize.

Setup Tips

Focus Before You Mount

The BM100 has manual focus — a physical ring on the fixture head that adjusts beam sharpness at different throw distances. Once mounted on a high stand or truss, the focus ring is difficult to reach. Set your focus during sound check while the fixture is accessible: power on, select a gobo, project it onto a target surface at your expected throw distance, and rotate the ring until the pattern is sharp. This 30-second adjustment makes a dramatic difference in how your gobo projections look — a focused gobo reads as intentional design, a blurry gobo reads as unfinished.

Learn Your Prism Speeds

The prism rotating at different speeds creates completely different looks. Slow rotation (10–20% DMX value range) creates an elegant, hypnotic spinning fan — great for atmospheric moments and slow songs. Medium rotation (40–60%) creates dynamic movement that reads well on dance floors. Fast rotation (80–100%) blurs the individual beams into a cone of light — high-energy but less defined. Experiment during setup to find the speeds that work for your show's different moods. Many operators keep the prism slow during verses and increase speed at choruses or drops.

Use the Prism Strategically — Not Constantly

The 8-facet prism is the BM100's most dramatic effect, which makes it tempting to leave it on the entire show. Resist that impulse. The prism has the most impact when it contrasts with moments without it. Slow single-beam sweeps → snap prism on at the drop → eight beams explode. That transition is the visual peak. If the prism runs all night, the audience stops noticing it. Toggle it on for high-energy moments, off for clean looks, and the contrast keeps every engagement powerful.

Pair Beams with Wash

Beam fixtures create drama but can't light a stage. The BM100's 3.6° output illuminates a tiny spot — great for mid-air effects, useless for general coverage. Pair with SF-MW710 wash fixtures for the color foundation, then layer BM100 beams on top for the dramatic accents. This beam-over-wash layering is how professional lighting designers build shows at every scale.

Master/Slave for Instant Multi-Beam Arrays

Four BM100s in master/slave mode, all with prism engaged: 32 beams from four fixtures. That's a wall of spinning light fans with zero programming. Cable them together, set one as master in sound-active mode, and all four react to the music in perfect sync. This is the fastest path to a visually impressive multi-fixture setup, and at $249 each, a 4-unit array costs under $1,000.

Pairs Well With

• SF-MW710 Mini Wash — Beam + wash is the classic pairing. BM100 for drama, MW710 for color. Under $400 per pair.
• SF-BM60 Mini Beam — Mix BM100s (with prism) and BM60s (without) in the same rig for visual variety. The BM60s provide clean single beams while the BM100s add multi-beam prism effects. Different looks from different fixtures makes shows more dynamic.
• SF-SP90 Gobo Spot — SP90 handles detailed gobo projection with dual wheels and rotating gobos. BM100 handles punchy beams and prism fans. Together, you cover both precision and power.
• Haze FX — The single best companion for any beam fixture. Light haze makes the 3.6° beam visible mid-air and turns the 8-facet prism into a visible eight-beam fan. Haze is what separates beam fixtures that project onto surfaces from beam fixtures that perform in space.
• Cold Spark FX — Colored beams illuminating spark fountains. Prism fans sweeping through rising sparks. The combination of tight beams and cold sparks is one of the most visually dramatic pairings in event production.
• All Stage Lighting — The BM100 is the mid-tier beam fixture that pairs with everything in the lighting catalog.
