Yeah - I'd say you're doing it right (now) - a dedicated LED controller with constant current drive is the way to go here imo. The current is within the limits of those small drivers, so you should be fine.
Usually when I think of driving LEDs, I'm driving either "pixel" style LEDs (WS2812, or WS2811 LED drivers with 1206 LEDs on them, so 20mA each), or I want bright light, so I'm using a 1W+ leds, at 350 or 700mA (or more)
