ok heres a link of the one i bought:

eBay.co.uk: GENUINE ENVIROLITE 125W GROW LAMP 6400K VEG (item 130103586687 end time 27-Apr-07 19:45:43 BST)

eBay.co.uk: ENVIROLITE HYDROPONICS LAMP HANGER GROW LIGHT NEW! (item 130104004793 end time 28-Apr-07 21:21:27 BST)

eBay.co.uk: GENUINE ENVIROLITE SINGLE LAMP REFLECTOR ! (item 130102209904 end time 24-Apr-07 22:22:34 BST)

DONT BUY ANY OF THE STUFF ABOVE!!

It is much better to buy this package which i didn't see at the time, it comes with the bulb and the fitting attached to the reflector whereas i had to buy it all seperately last time:

eBay.co.uk: MIRROR FINISH REFLECTOR WITH 125W ENVIROLITE 6400K LAMP (item 130105522048 end time 01-May-07 20:45:33 BST)

Here is the 250w one which will produce much better results if you can afford the little extra!!!! :

eBay.co.uk: MIRROR FINISH REFLECTOR WITH 200W ENVIROLITE 6400K LAMP (item 130105522127 end time 01-May-07 20:45:39 BST)

Hope this all helped
