The light can be used on 4 Seasons Azzurro, Siesta, Siesta Premium and Hacienda parasols. The 4-Seasons parasol lamp can be used with most parasols (with a pole thickness of 30 to 48 mm), thanks to the handy click system with spring, the lamp clamps around parasol posts. You hang light in the middle of the parasol on the cross tube attached to the ribs. Outdoor lighting for your parasol with 24 LEDs comes complete with 3 batteries and charger. The green indicator light indicates when it is fully charged. After this you can use the LED lighting for no less than 4 hours.
