Hey halo, here's a link to a 200 watt envirolite system, to show you what they look like, i got a 125w bulb for £20 and paid £10 for the fitting and cable from a local hydro store. Most hydro shops will sell them or there's loads of companies online that sell them, just do a google search for envirolite, also you can get them from ebay.

Peace :rasta:
