Solar Street Light 20 Watt - TTISSL20W
DiscontinuedSKU: TTISSL20W
This model is no longer manufactured.
The specifications below are kept for owners of existing installations.
The TTISSL20W is an integrated 20 W street light for society roads, internal lanes and parking areas — a straightforward fixture where MPPT is not required and the site has clear sun.
Coverage and sizing
Designed for a 5 m mounting height, with poles at three to four times that — roughly 15 to 20 m pole to pole. Confirm the pole-top has open sky through the middle of the day before fixing the layout: on this fixture the panel position is what determines whether the battery reaches full charge.
What is inside
20 W LED producing 3,200 lumens with Nichia chips, on a 32 Ah LiFePO4 battery charged by a 20 W panel. 3,200 lumens from 20 W is a high system efficacy, which is where branded chips earn their premium over unnamed ones. LiFePO4 service life is 8 to 12 years.
Autonomy and monsoon
32 Ah against a 20 W load is generous, and deliberately so: it is the reserve that keeps the fixture running across several consecutive overcast days rather than only the first.
Installation and warranty
Pole mounted, no grid connection, automatic dusk-to-dawn switching, IP65 housing. Two year warranty.
