Frequently Asked Questions

Can I use the ELG-100-42B with a PWM dimming signal from a lighting controller?

Yes. The ELG-100-42B supports 3-in-1 dimming: 1–10V analogue, PWM signal, and resistance dimming. A PWM input from a standard lighting controller or microcontroller will modulate the output current proportionally, allowing smooth dimming of 42V LED loads.

Is the ELG-100-42B waterproof enough for outdoor LED signage?

Yes. The ELG-100-42B carries an IP67 rating, making it fully sealed against dust and water immersion up to 1 metre for 30 minutes. This level of protection is appropriate for outdoor LED channel letter signs and lightboxes exposed to direct rain.

Can I run 42V dimmable LED strips for landscape lighting with the ELG-100-42B?

Yes. The IP67 rating and -40°C to +90°C operating range make the ELG-100-42B suitable for buried or ground-mounted landscape lighting installations. The 3-in-1 dimming allows integration with landscape lighting controllers that output a 0–10V or PWM signal. At 95.76W maximum, it supports approximately 9.5 meters of 42V strip rated at 10W per meter—verify your strip’s rated power per meter.

How does the ELG-100-42B differ from the ELG-100-42 base model?

Both share the same 95.76W / 42V / 2.28A output and IP67 waterproof rating. The ELG-100-42B adds 3-in-1 dimming capability (1–10V, PWM, resistance) that the base ELG-100-42 lacks. Choose the base model for fixed-output applications; choose the ‘B’ when dimming control is required.

Can the ELG-100-42B be used for dimmable outdoor architectural facade lighting?

Yes. The combination of IP67 sealing, wide temperature tolerance (-40°C to +90°C), and 3-in-1 dimming makes the ELG-100-42B practical for dimmable facade wash or grazing fixtures rated at 42V DC. The 95.76W output is sized for medium-scale facade lighting segments.
