Frequently Asked Questions
Can the ELG-75-C1050B be installed in fully outdoor LED luminaires exposed to driving rain?
Yes. The ELG-75-C1050B carries an IP67 waterproof rating, meaning it can withstand temporary immersion in water up to 1 meter for 30 minutes. This makes it suitable for outdoor area luminaires, floodlights, and LED fixtures mounted in exposed exterior locations.
Is the ELG-75-C1050B a good fit for LED floodlights used in sports or facade lighting?
Yes. The ELG-75-C1050B delivers 1050mA constant current within a 35–71V output voltage range at 74.55W total power. Its IP67 enclosure and -40°C to +85°C operating range make it a practical choice for outdoor LED floodlight applications on building facades or sports fields.
What LED loads is the ELG-75-C1050B compatible with?
The ELG-75-C1050B is a constant-current driver outputting 1050mA. It is compatible with any series LED string whose combined forward voltage falls within the 35–71V CC range; the number of LEDs that fit depends on each LED's forward voltage and cannot be stated as a fixed count.
Can the ELG-75-C1050B power LED modules in underground or below-grade lighting fixtures?
Yes. The IP67 rating means this driver tolerates temporary submersion, which is suitable for below-grade vault lighting, in-ground uplight fixtures, or other applications where water pooling is possible. Its sealed metal housing prevents moisture ingress in these demanding installations.
Does the ELG-75-C1050B support dimming, and how does it differ from the ELG-75-C1050A?
Yes. The 'B' suffix indicates this model includes a dimming interface for analog or resistance-based output adjustment. The ELG-75-C1050A provides adjustable output current only (no dimming signal input), while the ELG-75-C1050B adds a dimming control input. Both share the same 74.55W and 1050mA rating, but the ELG-75-C1050A is IP65 and the ELG-75-C1050B is IP67.
Is the ELG-75-C1050B suitable for LED street lighting or pathway lights in public infrastructure?
Yes. The IP67-rated, metal-cased ELG-75-C1050B withstands the outdoor temperature extremes (-40°C to +85°C) and moisture conditions encountered in street and pathway LED fixtures. Its 1050mA constant-current output ensures stable LED operation over long service periods.
