evergrow are pretty popular lights, but for one to cover 100cm you are looking at just over £300
if you look at second hand lights, you can pick up some bargains like the maxspect razor, radion XR30's or Hydra 26/52's
if you like having smaller profile lighting that still does the job, Kessil a360's again, some second hand bargains are out there or Kelo AO 100s ( look like kessils, not as good but a lot cheaper! )
I use a pair of zetlight za1201 with a twin controller and t5's and grow softies, LPS and SPS. They have a new one called UFO which looks pretty good.
