Hailuo AI launches Light Studio with 3-light relighting and HEX/Kelvin controls

• Hailuo AI has launched Light Studio, a still-image relighting tool with controls for light angle, intensity, color temperature, dual-source layering, and 20 presets, according to the launch post.
• The product pitch is less about regenerating a scene and more about reshaping the lighting on the same frame; Hailuo's follow-up demo frames it as directing the spotlight after the shot is already chosen.
• Early user demos suggest the control set goes deeper than presets alone: one tester highlighted HEX-code and Kelvin input for finer color tuning in a translated early-access post.
• Creator reactions also point to multi-light setups on top of the preset system, with one early tester saying their test allowed control of up to three lights.

Hailuo is positioning Light Studio as an image relight feature inside its video platform, with a free-trial entry point through the relight tool page. The core controls named in Hailuo's launch post are angle, intensity, and color temperature, plus dual-light layering and 20 one-click presets.

The more interesting part is the workflow framing. Hailuo's follow-up post pitches the tool as changing the mood of an existing frame instead of rebuilding composition, which makes it read more like a fast look-dev surface for key art, character stills, and product shots than a full image generation step.

Hailuo's UI teaser emphasizes direct manipulation, showing relighting as a click-and-drag adjustment rather than a prompt-only operation. That matters for artists who already know the shot they want and just need to push depth, contrast, or time-of-day feel.

Support posts add two useful specifics. In the Japanese early-access writeup, a creator says Light Studio supports both HEX-code and Kelvin-based color temperature input, which would make it easier to match brand palettes or practical lighting references. Another early test, described in a creator repost, says the tool can control up to three lights, extending beyond the dual-source layering Hailuo names in its launch copy.

The first wave of demos focused on how far one source image can stretch. In a reposted test, a creator uploaded a single image of samurai armor on white and ran multiple templates to produce dramatically different lighting moods, with the reflective metal helping show how strongly the relight changes read.

Another reposted early preview, the sneak peek, explicitly calls this “Image Relight,” reinforcing that the feature is built around post-lighting a provided still. Hailuo's own anime-look example also suggests presets are tuned for stylized looks, not just neutral correction, so the immediate use case is mood iteration as much as technical cleanup.
