Lamp common sense: the correct use of lighting fixtures

A) If the power supply voltage is too high, it can shorten the lifespan of both the ballast and the lamp. It may also lead to overheating and potential damage.

B) Conversely, if the voltage is too low, the lamp may not light up at all or operate inefficiently, reducing its overall life. The acceptable voltage variation for fluorescent lamps is within ±6%, while for HID lamps, it is typically ±6% (with a tighter ±5% requirement for metal halide lamps).

2. Choosing the Right Lamps

Selecting the appropriate lamp type depends on the environment in which it will be used. For instance:

- Rainproof areas (such as eaves or outdoor spaces) require rainproof luminaires.

- Areas where flammable gases are present (like oil or chemical plants) need explosion-proof or pressure-resistant fixtures.

- Moisture-prone locations (like bathrooms, basements, or underpasses) require moisture-proof lamps.

- Corrosive environments (such as chemical plants or hot springs) demand corrosion-resistant models.

- In cold areas (like freezers), use lamps designed for low-temperature operation. In places with vibration (such as gyms or factories), choose durable options.

For wet or damp areas outside the bathroom, always use waterproof lamps. These can be categorized based on their water resistance: moisture-proof, rainproof, or fully waterproof. Choose the right one according to the location's needs. In areas like eaves or house-side passages, humidity can reduce insulation and cause rust on reflectors—so moisture-proof and rainproof lamps are essential.

III. Installation Guidelines

A) Avoid placing luminaires too close together. Overcrowding can lead to excessive heat buildup, affecting performance and longevity.

B) High temperatures can cause the ballast to overheat, leading to reduced lifespan, bulb failure, or even cracking of the lamp holder or internal components.

C) Several factors influence the temperature of a luminaire, including the size, design, and materials used. To prevent overheating, follow these installation best practices:

(1) Maintain proper spacing between fixtures.

(2) Ensure adequate internal space for airflow.

(3) Provide ventilation holes around the lamp body.

(4) Avoid placing the ballast inside the fixture unless specified.

(5) Ensure good ventilation in the ceiling area.

D) Secure the installation position to avoid contact with flammable materials like curtains or fabric.

E) Keep lamps away from high-temperature sources, such as gas stoves. In kitchens, install lights at least 1 meter away from heat sources.

F) Rainproof luminaires must be installed in the correct orientation to prevent water ingress.

G) When installing moisture-proof and rainproof luminaires, pay attention to the following:

(1) Make sure the rubber gasket on the mounting surface is tightly sealed.

(2) If the surface is uneven, fill the gap before mounting the lamp.

(3) Check that the power cord outlet is not submerged in water.

H) When installing on reinforced concrete surfaces, ensure the surface is completely dry before proceeding. If the concrete is not dry, moisture can seep into the luminaire after installation, causing insulation issues and peeling of the lamp coating.
