With illumination levels of 425 lumens/foot, the Talea-HP provides lighting levels
equivalent to one 15-Watt halogen bulb every six inches, one 8-Watt (F8T5) fluorescent fixture every foot, or one 15-Watt (F15T8) fluorescent fixture every 18 inches.

Operation of the relevant control adjusts the lighting levels
to the pre-set scene which when required can be overridden to increase or decrease the lighting levels
Both sources increase site lighting levels
and enhance security without increasing the lighting load.
Of the options we explored, the Tersen Ratio PG LED luminaires were the only luminaires that would pay for themselves in four years, give us the lighting levels
