I have one fitted under the eaves, to light up the vast back garden area, when necessary via a remote control, which it isn't normally. Last time it was switched on, was when the police knocked at the door, asking if they could investigate a potential reported intruder, by next door.
In the drive, I have a big old HP sodium fitting, which likewise is only there for emergencies. I have a spare, identical 70w MH fitting, which just needs a replacement control gear, for which I have two new, spare lamps. My intention was, to take down the sodium, to replace it with the much neater MH fitting, if I could manage to repair the control, or source a replacement somewhere.
