Solar Bat Street Light 75 Watt - TTBAT75W

The TTBAT75W sits between the 60 W and 90 W fixtures, for wider internal roads and larger compounds where the 60 W is marginal at the required spacing.

Coverage and sizing

Designed for a 5 m mounting height, with poles spaced at three to four times that — roughly 15 to 20 m pole to pole. Where the road is wider than about 6 m, consider staggering poles on alternate sides rather than setting them in opposing pairs: a staggered layout covers more road from the same number of fixtures.

What is inside

75 W LED producing 2,760 lumens from 100 Nichia chips, on a 26 Ah LiFePO4 battery charged by a 25 W panel. LiFePO4 service life is 8 to 12 years. Panel, battery and LED are sized together: a larger LED behind the same battery would simply run out earlier in the night.

Autonomy and monsoon

26 Ah supports the fixture through several consecutive poor-weather days. Ask any supplier for autonomy in days at a stated depth of discharge rather than a general assurance — it is the only way to compare two quotations honestly.

Installation and warranty

Pole or wall mounted on a 2 inch GI pole, no cabling to the grid, automatic dusk-to-dawn switching, IP65 housing. Two year warranty.
