![]() ![]() ![]() Match value: B7c at 100% measured as 2720K with a -1/10 magenta shift. Source: LED lamp 12W at 100% measured as 2590K. However, when combined with the Sidus app’s SourceMatch feature, the app and light bulb combination does match nearly any white light source pretty accurately. When measuring at 100% output 40 cm distance, all three meters agreed within a 40K margin that the output was off - 180K at the lowest app setting and a whopping 2500K at the highest. I took measurements with an Illuminati M-100, M-150 and a Lumu Power Pro Gen.2, all three light/colour sensors that I connect to an iPad Air 2 and that have been developed specifically for LED lighting. However, the accuracy of the Kelvin values in the app for the light bulb is not something to brag about. The Accent B7c not being an ordinary light bulb is apparent from its ability to match the colour temperature range of the Nova P300c, Aputure’s most advanced colour mixing light, producing a wide colour temperature range of 2,000K-10,000K. With a frame rate of 240fps, there was not a flicker to be seen while the colour indeed remained the same throughout. Unique for a bulb that fits ordinary lamp shades, the B7c features 20KHz step-less dimming that remains completely flicker-free up to at least 1,000fps with no colour shift. #Cinema grade reviews skin#The B7c features a standard E26/27 fixture but unlike typical household LED bulbs, the lamp uses cinema grade LEDs to reproduce skin tones with CRI and TLCI values of 95+ and a tungsten SSI score of 85.Īputure claims the B7c bulb can produce over 90% of the saturated colours in the Rec.2020 colour space, which puts the bulb on par with industry-standard lighting instruments. It’s the first product in the new Accent family of LED lights built for filmmakers. The Aputure Accent B7c is a film bulb designed to fit into standard household light fittings making it ideal for colour accurate practicals.Īputure recently released the Accent B7c, a mains power and battery operated 7W RGBWW colour-mixing LED light bulb. ![]()
