Here’s what I found about 15 cm electric sparklers — specs, usage tips, and some example products. If you like, I can filter for ones deliverable to Chennai + show you prices.
What are 15 cm Electric Sparklers & What to Expect
A “15 cm electric sparkler” is a hand-held pyrotechnic sparkler ~15 cm (~6 inches) in length that produces bright “electric” or crackling / spark effects (usually silver/white) when ignited.
Because 15 cm is a moderate size, it typically offers longer burn time compared to 10 cm or 12 cm electric sparklers.
Many suppliers list duration ~15 seconds for their 15 cm electric sparklers. For example, Butterfly Crackers states “duration is 15 seconds.”
Safety & Usage Guidelines (for 15 cm Electric Sparklers)
Because it’s a stronger sparkler, safety becomes more important:
Hold at arm’s length, keeping the wire/stem pointing away from face, body, and clothing.
Maintain safe distance: spectators should stay several meters back (3–5 m is a good rule of thumb for larger sparklers).
Use in open or well-ventilated spaces, ideally outdoors.
Light one at a time per person; do not bundle multiple sparklers together.
After it burns out, place the still-hot wire in a bucket of water or on a non-flammable, heat-resistant surface until fully cooled before disposing.
Check certification / compliance: buy from reputable brands / suppliers that comply with local fireworks regulations (e.g. PESO in India).
Supervise children using them.
Storage: keep unused sparklers in a dry, sealed container, away from ignition sources.
