The Vipar XS 1500 Pro, the new model, is stunning. Arguably the best light in the 2' market and they sell them in pairs for a 2' x 4' that'll run you $200±.
I use Growcraft lights, one for veg and one for flower, and, while those lights put out huge amounts of photons, a pair of XS 1500 Pros will get you about 80% where for about 25% of the price. That light is really a stunner.
Full disclosure - I do have the XS-1500, the older model, that I use for fill lighting but the Pro, which is new this year, blows it away.
