Common questions about manuals, registration, and support for this brand.
No, standard electronic LED power supplies are generally not compatible with 120-volt AC dimmer switches. Use only Armacost Lighting low-voltage LED dimmers for brightness control, or check if your specific driver model is rated as a 'dimming LED driver.'
Voltage drop causes reduced brightness at the end of long strips. To fix this, shorten your DC power feed wires, switch to a heavier gauge wire (lower AWG number), shorten the length of the LED tape run, or use an additional power supply.
Yes, most Armacost LED tape lights can be cut to size. Look for the copper pads or silver solder joints marked on the tape (often with a scissor icon) and cut directly in the center of these pads.
