Two outputs, one family
Same body, same mount, same console workflow — pick the output that fits the set.
The G300Bi and G500Bi were built for crews who light a different room every week. Both heads share the same rugged body, Bowens mount and DMX512 workflow, so a two-light kit behaves like one system — set your key with the 300 W and add the 500 W as a punchy backlight, or push it through a big source as the main light.
G300Bi
Plenty of punch for portrait studios, interviews and small stages.
- Output300 W
- Luminous flux30,000 lm
- Illuminance @1 m, bare7,350–10,400 lux
- Weight2.05 kg
G500Bi
More than double the output once the set gets big or the diffuser gets heavy.
- Output500 W
- Luminous flux53,000 lm
- Illuminance @1 m, bare16,320–21,100 lux
- Weight2.45 kg
Control it your way
An LCD readout and one knob set power and colour temperature in seconds. Eight built-in effects cover lightning, TV flicker, flash and more, and a single key recalls your saved settings. Hand the whole rig over to a console whenever the shoot calls for it.
Rig it, shape it, shoot
Bowens mount and umbrella slot on every G head, so the lanterns, softboxes and grids you already own go straight on. That is also when the 500 W version earns its keep — a big diffuser eats output, and you still want f/8.
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.
On set, not only in the studio
Stepless 0–100% dimming and a 2700–6500 K range that tracks the room — the same head covers a lit interior, a night exterior and a stage grid.
Built for the Bowens ecosystem
Standard Bowens mount and umbrella slot — pair the G series with the full Golden Eagle light-shaper range.
