Frequently Asked Questions
Can the ELG-100-C500B be used in outdoor LED area lighting that requires dimming?
Yes. The ELG-100-C500B is IP67 waterproof and supports three-in-one dimming (1–10V, PWM, and resistance), making it well suited for dimmable outdoor area lighting, floodlights, or parking structure luminaires where weather exposure and dimming control are both required.
Is the ELG-100-C500B a good choice for dimmable LED downlights in a hospitality or hotel environment?
Yes. It delivers a constant 500mA across a CC voltage range of 100–200V and accepts 100–305VAC, covering all international mains. The built-in dimming inputs allow connection to standard 1–10V or PWM dimming systems typical in hospitality lighting control.
What operating temperature range does the ELG-100-C500B support, and does it affect installation location?
The driver is rated from -40°C to +90°C, accommodating installations in both cold outdoor environments and hot enclosed luminaire spaces. Combined with its IP67 waterproof metal case, it can be mounted in harsh locations including outdoor fixtures, industrial enclosures, and cold-storage lighting.
How does the ELG-100-C500B differ from the ELG-100-C500AB for use in a project requiring dimming?
Both drivers support the same three-in-one dimming inputs (1–10V, PWM, resistance) and share identical 100W, 500mA, 100–200V CC output specs. The key difference is IP rating: the ELG-100-C500B is IP67 (waterproof for outdoor or wet locations) while the ELG-100-C500AB is IP65 (water-jet resistant, for semi-outdoor or indoor). The C500AB also adds a current adjustment potentiometer that the C500B does not include.
What determines how many LEDs I can connect to the ELG-100-C500B in a series string?
The driver's CC voltage range of 100–200V defines the allowable total forward voltage across the LED string. The actual LED count depends on the forward voltage of each individual LED in your design — sum the forward voltages and ensure the total falls within 100–200V. The driver will then regulate the string at a constant 500mA.
