the one with independant solar panels will cost too much to install and my conpany dont have the budget to do so.
the idea i had of rearanging the lighting is still being considered but in my opinion i think that it will require some kind of contractors or lifting equipment in order to move the posts therefore it might be out of budget.
the best idea i think is to use the retro fit led lamps and just change them out for them.
i will be doing a costing for the running costs and compare it to the existing lights, i will also look into how long it will take for the savings to pay back the cost of the change.
