Godox KNOWLED MG4K Walkthrough Video Breaks Down the High-Efficiency LED

Godox has launched an in depth walkthrough video for the KNOWLED MG4K, providing an in-depth take a look at the two,000W bi-color COB fixture that the corporate positions as a 4K HMI equal. We first lined the MG4K again in September and mentioned it at IBC 2025, however this new video from Godox ambassador David Valente supplies extra context on the fixture’s effectivity claims, thermal design, and sensible setup workflow.The walkthrough arrives because the MG4K reaches wider availability, giving potential patrons and rental homes a better take a look at what Godox describes as class-leading effectivity within the high-output LED section. For individuals who missed our earlier protection, the fixture attracts 2,000W whereas claiming output similar to conventional 4K HMI items that require twice the ability consumption.Effectivity claims explainedThe video addresses a query many gaffers and DPs have been asking: how can a 2,000W LED match a 4K HMI? In line with Valente, the reply lies within the MG4K’s COB effectivity ranking of 110 lumens per watt. He notes that whereas some competing COBs function within the 60-80 lm/W vary, this increased effectivity permits the fixture to generate extra usable gentle from much less energy consumption.Valente makes an attention-grabbing level about how the business evaluates lighting output. For years, wattage served as a dependable shorthand for brightness, however as LED effectivity improves, this metric turns into much less significant. Godox opted for HMI equivalency naming as a result of it resonates with skilled crews who use HMIs as their reference level for high-output lighting.The sensible profit extends past uncooked output numbers. Operating on 2,000W means the MG4K can function on a typical 20-amp family circuit, eliminating the necessity for devoted energy distribution that conventional 4K HMIs require. For location work, this interprets to less complicated logistics and doubtlessly smaller generator necessities.The Godox KNOWLED MG4K attracts 2,000W and supposedly matches the output of a 4K HMI. Picture credit score: GodoxThe 63mm COB and optical performanceOne element emphasised within the walkthrough is the MG4K’s 63mm light-emitting floor, which Godox describes because the smallest in its class for this output stage. A smaller COB acts as a better approximation to a degree supply, which has vital implications for optical equipment.When used with the non-compulsory MGR15 15° reflector, the fixture produces 124,000 lux at 5m at 5600K, representing a 36.7x brightness enhancement over the open-face output. The 30° MGR30 reflector delivers 25,600 lux on the identical distance and shade temperature. This focus issue relies upon closely on having a compact gentle supply that sits exactly on the reflector’s focus, which is the place the small COB diameter turns into advantageous.The fixture’s 110° native beam angle supplies broad, even protection when used with out modifiers, making it appropriate for bounce lighting or filling giant areas.Thermal administration for prolonged shootsThe walkthrough dedicates vital consideration to the MG4K’s cooling system, which Godox claims improves warmth dissipation by 67% in comparison with earlier designs. Valente describes this as important for sustaining constant shade and brightness throughout lengthy capturing days.Excessive-output LEDs face a basic problem: pushing extra lumens from a compact COB generates substantial warmth, which may trigger shade shift and lowered output if not managed successfully. The MG4K’s Superior Mixing Structure goals to attenuate vitality loss whereas stopping the thermal buildup that degrades efficiency over time.Each the sunshine head and separate controller carry IP65 rankings for mud and water resistance. As we mentioned at IBC 2025, this climate sealing opens up exterior capturing prospects with out requiring extra weatherproofing measures. Notably, some sources checklist the ranking as IP67, so crews ought to confirm the precise specification for his or her particular use case.The Godox Knowled MG4K. Picture credit score: GodoxControl choices and connectivityThe walkthrough video demonstrates the MG4K’s management pathways by means of its separate gentle controller unit. Choices embody wired DMX for conventional reliability, wi-fi DMX through Lumen Radio CRMX for cable-free operation, and Ethernet connectivity supporting each sACN and Artwork-Internet protocols.For less complicated setups, Bluetooth management by means of Godox’s telephone app is out there with NFC pairing, permitting customers to faucet their telephone in opposition to the fixture for computerized connection. The controller’s separation from the sunshine head improves weight distribution throughout rigging, a sensible consideration when positioning high-output fixtures overhead.Shade management spans 2,800K to 10,000K with ±100% inexperienced/magenta adjustment, offering the pliability to match combined lighting situations or dial in exact shade replica. The fixture helps 0.1% dimming steps for wonderful brightness management.G-Mount modifier ecosystemThe MG4K makes use of Godox’s G-Mount system, which the corporate describes as providing the most important modifier ecosystem within the business. The walkthrough exhibits the 30° reflector being hooked up, demonstrating the quick-release mechanism.Appropriate equipment embody reflectors in a number of beam angles (15°, 20°, 30°, 45°), BeamLight attachments, Fresnel lenses together with a motorized possibility, projection attachments, numerous softbox configurations (parabolic, rectangular, octa, lantern), adjustable diffusion panels, and Liteflow reflectors. This 16-modifier ecosystem supplies in depth shaping choices for various manufacturing necessities.There are many totally different modifiers out there for the Godox KNOWLED MG4K. Picture credit score: GodoxPricing and availabilityThe Godox KNOWLED MG4K bi-color is out there for $4,299 USD, whereas the MG4K K1 equipment with flight case is priced at $4,499 USD. Godox positions the fixture as accessible to owner-operators slightly than solely rental homes, although the value level nonetheless represents a major funding for smaller productions.As we famous in our IBC protection in regards to the gentle, Godox additionally previewed a brand new shade engine system known as “Palette” throughout the present, which guarantees enhanced shade rendering traits for future fixtures.Have you ever had an opportunity to make use of the MG4K on a manufacturing but? How does it examine to conventional HMIs in your workflow? Don’t hesitate to tell us within the feedback beneath!
