Advantages and disadvantages of stage lights with different types of bulbs and their selection

Advantages and disadvantages of stage lights with different types of bulbs and key points for selection

First, LED stage lights

Advantages:

High brightness and energy efficiency: It can provide sufficiently bright lighting effects in large performance venues, and its energy consumption is much lower than that of traditional lamps.

Rich in color: The color of the light can be adjusted by controlling the color temperature and brightness to create a wide variety of lighting effects.

Long service life: The service life can reach over 100,000 hours, which is several times that of traditional lamps.

Environmental protection: It does not contain harmful substances (such as mercury), and has a small impact on the environment after being discarded.

Fast response speed: Short dimming response time, suitable for high-speed dynamic scenes.

Disadvantage:

Stroboscopic problem: Stroboscopic may occur when driven by alternating current. It is necessary to choose products equipped with high-quality driving circuits.

Limited irradiation Angle: Generally, it can only illuminate 120°, and the coverage area needs to be expanded through optical design.

High initial cost: Although the long-term usage cost is low, the initial purchase price is relatively high.

Key points for selection:

Confirm the dimming level (recommended ≥12-bit) and response time (≤30ms).

Check whether the heat dissipation design is reasonable to avoid light attenuation or malfunction caused by overheating.

Give priority to choosing products that support the DMX512 protocol and intelligent control systems.

Second, halogen lamp dance table lamp

Advantages:

Complete spectrum: High color rendering index (above 95), high color saturation, suitable for scenarios with high requirements for color reproduction.

Good light control: Small in size, suitable for projective lighting, and can precisely control the size and shape of the light spot.

Low price: Compared with LED lamps, the initial purchase cost is lower.

Disadvantage:

High heat generation: Most of the energy is lost in the form of heat, so attention should be paid to heat dissipation and anti-scalding design.

Short lifespan: The general service life is 2,000 to 4,000 hours, and the lamp beads need to be replaced frequently.

High energy consumption: Low light conversion efficiency and high long-term usage cost.

Key points for selection:

Choose lamps with anti-scald design to ensure safe use.

Confirm whether the lamp supports the brightness adjustment function to meet the needs of different scenarios.

Pay attention to the color temperature selection (halogen lamps have a warmer color temperature and may not be suitable for all scenarios).

Third, fluorescent stage lights

Advantages:

High luminous efficiency: It can reach 50-100 lumens per watt, which is much higher than that of incandescent lamps.

Low heat generation: Small heat energy loss, suitable for long-term lighting scenarios.

Long lifespan: The typical lifespan is 6,000 to 15,000 hours.

Disadvantage:

Mercury pollution: Each lamp tube contains 3 to 5 milligrams of mercury. Improper disposal can cause environmental pollution.

Startup delay: Traditional inductive ballasts require a startup time of 0.5 to 3 seconds, which is more obvious in low-temperature environments.

Stroboscopic problem: A working frequency of 50/60Hz May cause visual fatigue.

Key points for selection:

Give priority to choosing products equipped with electronic ballasts to reduce startup delay and stroboscopic problems.

Confirm whether the lamp supports use in low-temperature environments (avoid failure to start below -10℃).

Pay attention to the disposal methods of waste to avoid mercury pollution.

Fourth, gas discharge lamp dance table lamp

Advantages:

Extremely high brightness: Suitable for scenarios that require strong light sources (such as large-scale concerts and outdoor performances).

Beam concentration: It can produce a sharp light column effect, enhancing the visual impact.

Disadvantage:

Long startup time: Preheating is required to reach the rated brightness.

Shorter lifespan: Compared with LED lamps, its service life is shorter.

High energy consumption: Low light conversion efficiency and high long-term usage cost.

Key points for selection:

Confirm the startup time and preheating requirements of the lamps to avoid affecting the rhythm of the performance.

Check whether the heat dissipation design is reasonable to ensure the long-term stable operation of the lamps.

Give priority to choosing products that support dimming function to meet the needs of different scenarios.

Fifth, comprehensive purchasing suggestions

Clarify the usage scenarios:

For theatrical/drama performances: LED lamps should be given priority, with emphasis on color reproduction and dimming accuracy.

Concert/Concert: Gas discharge lamps or high-brightness LED lamps can be selected to emphasize the beam effect and dynamic performance.

Television/film shooting: To avoid stroboscopic problems, it is necessary to give priority to choosing LED lamps that support high-frequency PWM dimming.

Focus on core parameters:

Dimming levels, response time, and brightness consistency.

Heat dissipation design and protection level (such as IP65 or above, suitable for outdoor use).

Testing and Verification

Demonstrate the lighting effect on the spot, observe the uniformity of the light spot, the naturalness of the color transition and the dynamic response speed.

Simulate long-term operation to check whether the heat dissipation system is effective and whether the lamps show flickering or brightness attenuation.

Consider the long-term cost:

Although LED lamps have a high initial cost, they have a low long-term usage cost (low energy consumption and long lifespan).

Halogen lamps and fluorescent lamps have a low initial cost, but the cost of replacing lamp beads and energy consumption needs to be taken into consideration.
