Well the reviews on the latter say it isn't much good.

Decide how much lighting you want.
- SON re industrial sodium yellow light
- Fluorescent re conventional warm-cool white light

Decide how you want to control them.
- Single industrial photocell on wall switching the lot
- Individual photocell integrated into each light unit

Lights with integrated photocell provide better reliability at higher
cost, industrial photocell (box on a wall) are however quite reliable.


Ebay had some Coughtrie cbc IP65 photocell fluorescent lights for
£9-14, diecast aluminium opal diffuser, normally £45 normally as
proper industrial lighting gear. Nothing like them on there now
unfortunately as the price was excellent. Do not use the ASD bulkhead
photocell, they used to fail quite often.

Going for "real" IPx4 or IPx5 is a good idea re fit-n-forget. Go to
any electrical wholesalers and see what they have.
