thanks in advance,

what is your battery and Led spec?
The transistor should be used with only a current gain of 10. Higher rated devices will have a lower ESR and drop voltage.

Collector-emitter saturation voltage VCE
(sat) IC
= 500mA, IB
= 50 mA 0.6 V
Base-emitter saturation voltage VBE
(sat) IC
= 500mA, IB
= 50 mA 1.2 V
