Wiring is commonly offered in brown or green. Lead cord lengths are typically 24 inches or 36 inches; some sets list cord end lengths of 24 inches or 6 inches.
Chili string lights use mains electric power (no batteries). Several sets list 120 volts at 60 Hz, drawing about 0.12 amps and about 14.4 watts per set.
Many sets are UL listed or described as approved for both indoor and outdoor use. Some listings specifically call out sheltered outdoor use, while others state general outdoor suitability—check the individual product listing for exact wording.
Bulbs are mainly described as incandescent. Listed bulb shapes include T5, miniature T1.75 and 3mm; some entries label the 3mm bulbs as LED.
Some listings state you can connect up to 14 sets end-to-end for a total run of 161 feet on one plug. Those examples list a per-set draw of 14.4 watts (0.12 amps) and include an overall limit note not to exceed 210 watts.
Materials reported include plastic for the chili-shaped light covers, copper wiring on some sets, and glass bulbs in some listings. Other descriptions use generic terms like 'wire' and 'bulb materials' without further detail.
