Frequently Asked Questions
Can I use the HLG-40H-24B to power 24V LED strip lighting outdoors?
Yes. The HLG-40H-24B outputs 24V at up to 1.67A (40W) and carries an IP67 waterproof rating, so it can be mounted in locations exposed to rain, snow, or temporary water pooling. Its aluminium casing and -40°C to +80°C operating range handle harsh outdoor conditions year-round.
Is the HLG-40H-24B suitable for dimmable 24V landscape lighting?
Yes. The HLG-40H-24B includes a 1-10V/PWM dimming input, allowing you to pair with a compatible dimmer to adjust brightness for garden path lights, accent lighting, or other 24V landscape fixtures. Its IP67 waterproof rating makes it reliable for in-ground or exposed mounting.
Can I use the HLG-40H-24B to drive a small 24V LED channel-letter sign?
Yes, as long as the sign modules draw no more than 40W total at 24V. The HLG-40H-24B operates in constant-current mode with a CC voltage range of 14-24V, so it accommodates modules that may run at slightly lower voltages. The IP67 rating is well-suited for exterior-mounted signs.
How many meters of 24V LED strip can the HLG-40H-24B drive?
It depends on your strip's power consumption per meter. The HLG-40H-24B provides up to 40W at 24V. For a strip rated at 10W/m, you could run 4 meters (40W / 10W per meter = 4m). For a 5W/m strip, up to 8 meters. Always check your strip's rated power per meter and stay within 40W total.
Can the HLG-40H-24B handle being installed in a wet underground junction box?
Yes. IP67 means the enclosure can withstand temporary immersion in water up to 1 meter deep. It is suitable for underground vaults, wet junction boxes, or any location where standing water may occasionally occur. The -40°C to +80°C operating range also covers extreme temperature environments.
