Why Are Photography Lights So Expensive? Isn't It Just A Light Bulb?
Simplified, there are three aspects, which are also the three core technologies of great video maker :
1. Full spectrum, similar to sunlight
If the color under the light is accurate, the color in the camera is the same as in reality, then the lighting of the object must be professional, with a color rendering index of 95 or more, and the visible light spectrum is complete and continuous, ensuring that all colors visible to the naked eye can be seen. Exactly, why is there a color difference between the clothes under the light and the clothes in reality?
Either it’s a phone problem or a lighting problem. If you look at the light with your eyes, you can’t see the difference. It’s good if you think it’s bright, but you can tell by the contrast of the colors of the objects under the light.
The CRI of incandescent lamps is very high, but the energy consumption is high. Photographic lamps are often one or two hundred watts, two or three hundred watts. If incandescent lamps are used, the brightness of this wattage will not be enough, because photographic lamps need to be added with a soft box. Such accessories will reduce the brightness to a certain extent, and the light will become softer, so the brightness of the incandescent lamp will not be enough.
Professional photography light, high-tech LED lamp beads, 100W actual power, can reach the brightness of 1000W incandescent lamp, which is 10 times, this kind of light, no matter how to add accessories, can ensure enough brightness, why professional photography light The effect is good, because the photographic light has high brightness and no stroboscopic, so as to ensure clear picture quality and no noise.
2. Heat dissipation cost
High-power photography lights and LED lamp heads will generate high heat. If the temperature is maintained above 80 ℃ for a long time, one is unsafe, and the life of the lamp is not long, and it will burn out after a long time. Finally, professional photography is particularly concerned. The light effect will be deviated, and the light will be unstable, which is difficult to detect with the naked eye, but the high-definition device will capture it. The color temperature may be deviated, and the white light will become warmer or whiter. White balance, the color temperature of the front and rear images will be different.
The video light also needs to take into account the problem that some shooting scenes need to be radioed, and cannot just rely on the built-in fan to dissipate heat, such as GVM-G100W This 90W photographic light uses a high-quality radiator and a built-in ultra-quiet fan cooling system. It is designed with an aviation aluminum alloy shell, and it is silent to dissipate heat, so that the maximum temperature of the light does not exceed 70 °C, so as to ensure light efficiency and effective Improve the heat dissipation and environmental overheating during complex shooting, better protect the COB lamp beads, and prolong the service life of the lamp.
3. Power supply method
This is also one of the costs. For photography and videography, the venue changes at any time. Unless there are long-term studio lights in the studio, it is generally moved wherever it goes, sometimes indoors, sometimes in the wild, in order to facilitate various needs, GVM lights all provide dual power supply, and some are also powered by lithium batteries.
That is to say, when indoors, the AC power supply takes priority, and the 220V socket can be used as soon as it is plugged in.
Outdoors, when there is an external battery or the kind of power supply box commonly used by the crew, you can connect the DC port to supply power and fill light.
When there is no external battery and power supply box outdoors, the light body’s own lithium battery is used for power supply. Generally speaking, the always-on light uses a lithium battery, which is not very powerful. There are also many lithium batteries for high-power photography lights. Power supply, because the always-on high-power photography light is really very power-hungry, or the external battery or power supply box is reliable.
If you really analyze the photographic light from a professional point of view, you can understand the difference between it and the ordinary light bulb.
And GVM is also in the field of professional lighting, which is very cost-effective. Photography friends can learn more and try it out, such as these SD200R, G100W and P80S professional photography continuous lights:
