What is the difference between professional video/photographic lamps and ordinary household energy-saving lamps?
As a professional lighting research and development manufacturer with 11 years of experience in the film and television lighting industry, Benwei will analyze the difference between professional film and television lighting and ordinary household energy-saving lamps.
1. Brightness
The brightness required by film and television lighting varies according to different shooting scenes. The decisive factor of brightness is power. Ordinary household lighting, the brightness is basically not very large, generally not more than 100W, and a 30-square-meter living room often needs to be installed. A few lights are used to keep it bright, and for film and television shooting scenes, sometimes it is necessary to take a panoramic view of the night scene. A high-power photography light can brighten the area within 200 meters. This is something that ordinary household energy-saving lamps cannot achieve.
2. Strobe
Ordinary energy-saving lamps for household use are powered by 220V AC, which is the standard for residential use. The lamp has no special technology and will produce stroboscopic light. As long as the camera is pointed at the household lamp, flashing horizontal stripes will appear, which is very useful for shooting. Fatal, and manufacturers such as households only need to control the strobe within a range where the human eye is not easy to fatigue, which is far from meeting the needs of photography, while professional film and television lighting has constant current technology and will not produce strobe problem.
3. Color rendering index
According to the national architectural lighting design standard GB50034-2013, the color rendering index (Ra) of the lighting source should not be less than 80 in the room or place where you work or stay for a long time. Therefore, for household lighting, only the general color rendering index Ra needs to be above 80, so that the naked eye can distinguish the color of the object under such light.
(Benwei light display index measured, the color rendering index of all hues of R1-R15 are higher than 90)
But this is not enough for photography and video equipment. Without high CRI, there will be chromatic aberrations in the pictures taken. For professional film and television lighting, the general color rendering index Ra needs to be above 90, while the Benwei brand photography lighting not only can guarantee the general color rendering index Ra to be above 95, but even the special color rendering index R9- which is avoided in other lighting products. R15 can also reach a high level of 90 or more, ensuring that the color of all objects in the picture captured by the photographic camera equipment can be the same as the actual color.
4. Adjustable power and color temperature
Generally, the brightness of ordinary energy-saving lamps for household lighting is determined by the wattage of the bulb itself, and there is basically no change. The color temperature is basically the white light color temperature of noon sunlight around 5500K. Very few desk lamps can adjust the brightness. And color temperature, but it is often not accurate enough, and it is easy to overheat and cause light effect deviation.
Professional film and television lighting, in order to meet the strict requirements of the photographer or director, the photography lamp and the power and color temperature need to be very accurate, and can be accurately adjusted in a portable way. For example, the Benwei dual color temperature photography light can be used to steplessly adjust the power of the photography light from 0-100% through the 2.4G remote control or mobile phone APP. The color temperature of the photography light can also be adjusted between 3200K-6500K to achieve cold light and warmth. Switch between light and white light effects.
5. Power supply
Ordinary energy-saving lamps for household lighting use AC power at home, either installed on the original lamp holder or plugged into the socket for use. Household lamps that are powered by batteries are rarely used, except for flashlights. Benwei’s dual-power-powered photography lights can be plugged into sockets at home, and batteries can still be used for outdoor shooting. There is no restriction on the creative venue.
6. Scene light
Professional photography lights such as the Benwei brand will generally stand from the director’s point of view, and according to the director’s needs, preset several scene lights commonly used in filming, TV series or short videos, such as police cars, fireworks, televisions, and lightning. Wait, in the process of video shooting, you only need to use light to achieve immersive effects, which are not available in ordinary household lighting.
7. IPL
In order to create an atmosphere or need creative lighting elements, some photographers need to buy professional RGB full-color photography lights to provide color light elements. As mentioned above, household lighting is basically white light of about 5500K, only bars, stages, etc. Color lights will appear in special places. Benwei's RGB colorful lights are all equipped with 360 hues, which is a large color warehouse.
8. Use of light effect accessories
For professional film and television lighting, creators usually need to add some accessories to control the direction of the light, soft or hard light, spotlight or floodlight, etc., to achieve the lighting effect that the creator wants, so the light panel of the photography light will be Equipped with a bayonet, it is generally common. For example, the Benwei camera light is equipped with a Baorong bayonet, so that it can be compatible with all the lighting accessories of the Baorong bayonet. This is also impossible for household lights.
9. Flash and constant light
In addition, as far as photographic lighting is concerned, it is divided into flash and constant light. The flash has a large instantaneous discharge power and high brightness. The constant light is easy to control and is also used for shooting video lighting. However, the household lighting only has the constant one.
10. Photography lights are more energy efficient
Compared with household energy-saving lamps, photography lamps are actually more energy-saving under the same brightness. The measured data shows that an ordinary 100-watt lighting bulb can only achieve 1000lm luminous flux, and to achieve the same 1000lm luminous flux, the Benwei photography lamp only needs 10W The left and right power is one-tenth of the power required by household lamps.
11. Photography lights are more expensive
The last difference is the price problem that everyone often asks. I think after the above explanation, everyone should have a more specific understanding of the more expensive photography lights. How can the photography lights integrated with so many technologies be compared with ordinary ones? The home lights are at the same price level, and creators who really have high requirements for the quality of their works often don’t care about the price, but only care about whether they have higher lighting quality, and in the professional film and television lighting brand power, Benwei Lighting’s The market price is already very, very kind.
Therefore, not all lights that emit light can be used as photography lights! Good lighting needs to choose an old brand like Benwei who has the qualifications and masters the core technology!
