Most are made to fit standard holders: about 1.5 inches in diameter and roughly 1.4–1.7 inches tall. Some smaller styles are about 0.75 inches high.
They are often made of plastic or resin; some models feature a wax-dipped or wax-like finish to create a more realistic candle appearance.
Battery life varies by model and battery type but commonly falls in the range of about 100 to 200 hours of continuous illumination.
Common pack sizes include 6, 12, and 24 tea lights or votives per pack.
Typical switches are twist-to-turn and push-button; a few listings also use an on/off sliding switch.
Listings commonly show indoor use and some note suitability for indoor/outdoor decoration. At least one listing explicitly states the lights are not waterproof, so check each product's description for outdoor use and waterproof ratings.
They produce no dripping wax, smoke, or open flame and don't require matches, reducing mess and fire risk. Several listings note they are suitable for use around children and pets.
