Two outputs, one family

Same body, same control set, same Bowens mount — pick the wattage your stage asks for.

The M series is our high-output family for working sets. M550Bi and M850Bi share one body platform, one console workflow and one mount, so you can scale a rig from a two-head interview to a full stage grid without re-learning anything — and the included carry bags are sized for real travel, not just shelf appeal.

500 W

M550Bi

The compact workhorse. Room-filling output that still travels in the included carry bag.

Luminous flux53,000 lm
Illuminance @1 m, bare16,320–21,100 lux
Weight3.8 kg

800 W

M850Bi

The heavy hitter. When you light through big diffusers or bounce off ceilings, this is the one.

M550Bi and M850Bi controlled from the Golden Eagle app

Control it your way

A rear knob sets power and colour temperature in seconds, your phone mirrors the whole fixture, and a DMX512 console can take over at any time. Eight built-in effects cover lightning, TV flicker and flash — one key recalls your saved look.

M series fixtures rigged with parabolic and strip softboxes in a photo studio

Rig it, shape it, shoot

Bowens mount and umbrella slot as standard, so the parabolics, lanterns and strips you already own go straight on. That is also where the 800 W version earns its keep — a big diffuser eats output, and you still want f/8.

High CRI versus low CRI colour comparison

Colour you can trust

CRI>96 and TLCI>97 across the whole colour temperature range. Skin tones stay natural, product colours stay true, and the grade holds up take after take.

That consistency comes from a tightly binned COB engine and drivers that hold output stable across the full 0–100% dimming range — no colour shift as you dim, no surprises when you cut from take one to take forty.

M series fixtures lighting a rooftop interview after dark

On location after dark

Stepless 0–100% dimming across 2700–6500 K — the same head covers a warm terrace interview, a night exterior and a stage grid.

A bare M850Bi still throws 22,000 lux at one metre — enough headroom to fight dusk, light through heavy diffusion, or carry a key across a courtyard without rigging scaffolding.

Built for the Bowens ecosystem

Standard Bowens mount and umbrella slot — pair the M series with the full Golden Eagle light-shaper range.
