When I first started I bought a 150W MH from Lampman.co.uk. Since then I have come to the conclusion that 250 may be a better idea so I approach lampman again but the contact number etc are no longer working. They are now trading under www.trilight.co.uk on 0845 130 8494. I had a word with Graham there and said he could do a geartray (ballast, capaciter, ignitor and lamp holder all wired up) with a 250w 4200K double neded for about £50 plus shipping of about £10. He can do other wattages as well, he seemed intersted in what we do and may get around to one himself if he gets time. I thought it may be a useful contact for us this side of the pond.
