Lightpro Track Light 40B Variable Colour LED for Track Light track

LightPro GK-40B TRACK SlimLine Pro — Redefining the Professional Standard

Engineered for uncompromising cinematographers and high-volume broadcast studios, the LightPro GK-40B TRACK SlimLine Pro delivers flawless variable-color illumination and seamless grid integration in an ultra-slim, architectural-grade chassis.

Engineered for Elite Studios, Trusted by Industry Leaders

In the uncompromising arena of closed-set soundstages and top-tier commercial productions, lighting must be both flawless and hyper-efficient. The LightPro GK-40B TRACK SlimLine Pro disrupts traditional overhead grid workflows by offering an innovative, modular track-based mounting and power system. Forged from an ultra-thin, aircraft-grade aluminum alloy, this fixture provides exceptional thermal dissipation while maintaining an incredibly low-profile footprint. This allows studio designers and Directors of Photography to maximize vertical space on set without sacrificing structural integrity or overall output.

At the core of the GK-40B is an advanced color science architecture engineered to meet the strictest global broadcast standards. Delivering an exceptional CRI of 97.25 and a TLCI of 98.27, this fixture guarantees pristine skin tone rendering and absolutely zero color shift. The stepless variable color temperature range from 3200K to 5600K ensures seamless matching with existing practicals, ambient environments, or daylight sources. Paired with a built-in diffusion panel and highly responsive, professional-grade barndoors, the light can be shaped and cut with clinical precision, ensuring your subject is beautifully sculpted while keeping spill completely off unwanted set elements.

Designed for the relentless, high-pressure pace of modern production, the GK-40B offers uncompromised workflow versatility. It runs effortlessly on direct DC mains for continuous studio hours or utilizes dual Sony NP-style batteries for dynamic, tetherless agility when required. With an integrated 2.4G wireless control system supporting 99 discrete channels, gaffers and studio managers can execute sweeping lighting adjustments across an entire soundstage from over 40 meters away. This is not just a light panel; it is a meticulously crafted production tool designed to elevate the standard of elite cinematography.

Professional Integration FAQ

How does the GK-40B integrate into high-density overhead studio grids without creating cable clutter?

The unit is purposefully engineered to mount seamlessly into the proprietary LightPro 1.5m track system, utilizing the track for both secure overhead suspension and direct power delivery, entirely eliminating the need for individualized, messy cable runs across the grid.

Can the fixture maintain photometric consistency across a full day of continuous broadcast filming?

Yes. The ultra-thin aluminum alloy housing acts as a highly efficient passive heatsink, ensuring the internal LED architecture maintains optimal operating temperatures for a locked-in TLCI of 98.27 and zero color shift during grueling, back-to-back 12-hour production cycles.

What level of precision does the wireless control module offer for multi-fixture soundstages?

The integrated 2.4G wireless system operates across 99 independent channels, allowing board operators and lighting technicians to make zero-latency micro-adjustments to CCT and intensity on individual fixtures or massive, synchronized lighting arrays from up to 40 meters away.

Is the beam profile suitable for critical tabletop or high-end product cinematography?

Absolutely. The built-in diffusion guarantees a beautifully homogenous, wrap-around light source out of the box, while the structurally rigid integrated barndoors allow for surgical flagging and definitive spill control on highly reflective luxury surfaces.
