Frequently Asked Questions
Can I dim LED string bulbs with any dimmer?
No. Use an LED-compatible dimmer or controller specified for the bulb type. Older incandescent dimmers can cause flicker or limited range with LEDs; check the bulb packaging for dimmer compatibility or choose a dimmer labeled for LEDs.
Are halogen PAR20 floods suitable for outdoor use?
Halogen PAR20s are typically designed for indoor or protected fixtures. They produce more heat and are not as weatherproof as outdoor-rated LED bulbs; for exposed outdoor fixtures choose weather-resistant LEDs or properly rated, sealed fixtures.
How do I match bulb size and fit for my string lights?
Check the socket type (C7/E12 vs C9) and physical bulb diameter. Measure spacing on your string and confirm replacement bulb packs match the original socket and clearance. HLO lists C7 and C9 replacement compatibility, but always verify before purchase.
