I've already got bulbs and ballasts, thank you though.
I've spoken to AH supply and they will ship JUST the reflectors each reflector for a 36pc is $16, £8 then $25 for postage, £12.50.
£12.50 is a lot of money ontop of £8, I was hoping I could spread the cost by finding people willing to go halves on an order thus halving the cost.
