Yes the vega is much better in controllability than the razor. When i mean color, i mean the corals color. Mainly because it seems like the vega lacks violets, while razor uses dual-core Violets. As for spectrum, vega uses cool white with a mix of color leds (red and green), while razor uses warm white (which consist of red and green too) which blends the light better. i personally think warm whites are better than cool white + red/green.
upon more research, it appears that the vega color/blue has the so called "deep blue color led", it may or may not be violets (410-430nm).
The razor is also cheaper while putting out higher wattage (120w vs 95w), better spread too. So IMO, the razor is a better choice here for me.
edit : and what i meant by overkill (adding another vega) im not talking about the wattage or the amount of light, im talking about the price. might as well top up a and get the best fixture, which is the GHL Mitras rather than get 2 vega.
