My favorite light, the Zylight Z90. Dial in any color you want without gels or filters! Fully dimmable without color shift. Presets for indoor and outdoor. Digital readout. Dial in color temperature from 2500k to 9000k. This is one serious little lamp that is very useful on and off camera. You need a serious battery, too, so don't bother pulling out your AA's. Ask momma and daddy for a contribution because this unit weighs in at around 900 US $
But then, it will last you a lifetime and is really not comparable to any eBay lamp out there: builtwise nor functionally. This is part of a pro kit.
