The floodlight is a point light source that can illuminate uniformly in all directions. Its illumination range can be adjusted arbitrarily, and it appears as a regular octahedron icon in the scene. Floodlights are a widely used light source in the production of renderings. Standard floodlights are used to illuminate the entire scene. Multiple floodlights can be used in the scene. In order to produce better results, the light bulb for shooting is installed in a large reflecting umbrella for use as a high-brightness diffused light source. Although it is indispensable for indoor lighting, it can also be regarded as one of the light sources with good lighting effects for ordinary amateur indoor photography.

As a replacement product of electric light sources, floodlights have been recognized by more and more people and have been applied in many fields. Its main features are as follows:
1. Long lifespan: Normal incandescent lamps, fluorescent lamps, energy-saving lamps, and other gas discharge lamps have filaments or electrodes, and the sputtering effect of filaments or electrodes is an inevitable component that limits the life of the lamp. The high-frequency electrodeless discharge lamp requires no or less maintenance and has high reliability. Compared with other lamps: 60 times of incandescent lamps; 12 times of energy-saving lamps; 12 times of fluorescent lamps; 20 times of high-pressure mercury lamps; the long life of floodlights greatly reduces maintenance troubles and replacement times , Saving material costs and labor costs, and can ensure long-term normal use.
2. Energy saving: Compared with incandescent lamps, energy saving is about 75%. The luminous flux of 85W floodlights is roughly equivalent to that of 500W incandescent lamps.
3. Environmental protection: It uses solid amalgam, which will not pollute the environment even if it is broken. It has a recyclable rate of more than 99% and is a truly environmentally friendly green light source.
4. No stroboscopic: Because of its high working frequency, it is regarded as "no stroboscopic effect", it will not cause eye fatigue and protect eye health.
5. Good color rendering: the color rendering index is greater than 80, and the light color is soft, showing the natural color of the illuminated object.
6. Optional color temperature: from 2700OK to 6500OK, customers can choose according to their needs, and can be made into colored light bulbs for garden decoration lighting.
7. High proportion of visible light: In the emitted light, the proportion of visible light is more than 80%, and the visual effect is good.
8. No preheating is required. It can be started and restarted immediately, and the light decay phenomenon in ordinary discharge lamps with electrodes will not be caused by multiple switching.
9. Excellent electrical performance: high power factor, low current harmonics, constant voltage power supply, and constant luminous flux output.
10. Installation adaptability: It can be installed in any position without restriction.

Refers to a light projector designed to illuminate a scene or object when the lighting requirements of the reference scene or object are much stronger than the background . Although it is indispensable for indoor lighting, it can also be regarded as one of the light sources with good lighting effects for ordinary amateur indoor photography.
