Godox FL15Bi vs Godox ML40R
Two of our picks from Best Godox Video Lights for Streaming and Vlogging: ML40Bi, ML40R, FL15Bi, LC500R and the EazyFlow Softboxes, compared side by side on the specs and trade-offs that actually matter.
Short answer
Between the Godox ML40R and the Godox FL15Bi, we recommend the Godox ML40R ($119 when we checked it on 2026-09-14) as the better godox video light for most people. The same key light with full RGB for the day it points at the wall. The Godox FL15Bi ($99 when we checked it on 2026-09-14) still makes sense if lighting a face on a night walk, held or clipped to a strap.

Our take on each
Godox FL15Bi
Best for: Lighting a face on a night walk, held or clipped to a strap.
The Godox FL15Bi is shaped like a torch and used like one: a bi-colour beam you hold or clip to a bag strap to light a face at night. It is the only light here with no USB-C desk mode, so it belongs in a bag rather than on a desk.
The beam is narrow, which is what you want at arm's length outdoors and not what you want on a desk. It is a new listing. Owners rate it 4.3 across its first 5 reviews.
Godox ML40R
Best for: The same key light with full RGB for the day it points at the wall.
The Godox ML40R is the ML40Bi with full colour. Same body, same battery, same USB-C, same app; the difference is an RGB mode with saturation control and a set of effects, so it can be a key light on Monday and a coloured background light on Tuesday.
As a key it performs the same as the Bi. As a background light it is small, so it colours a patch of wall rather than a whole room; for a wall, the LC500R tube spreads further. Buy the R only if the light will change jobs.
Owners rate it 5.0 across its first 4 reviews, which is to say it is new.
