I ordered this LED/baton light to see how it works with my present DC solar mini lighting system.
Initially i connected it to fully charged in warrenty 12V7ah exide UPS battery
exact observations whole night
1) 6pm ON till 7pm full bright
2) later now the light brightness is decreased a little bit (attaching image if option present)
3) at morning 5am not bad but the lighting luminous is exactly like u would have seen old style transformer bed lights on switch boards / now a days u might have found small LED strip type that luminous
simple, now a days most of the DC lights / torchs coming with luminous bright control
if any such 3 steps option is present on light not on switch it would be greatly helpful to use / conserve low battery / charge.
