We have four LED spot lights or down lights maybe, at 12V (AC/DC), 10W. (We don't have any more information unfortunately) We have them connected in parallel with a driver that outputs 15-34V at 1500mA. This driver also buzzes slightly in this setup, but we're not sure if that's a separate problem.
When we turn this on, the LEDs give a constant light, but at a very low luminosity. With only three LEDs in parallel on this circuit, the LEDs do a slow flicker (a couple of times a second perhaps).
We've tried with a different driver (22-38V, max 50V, 1050mA) and the 4 LED setup flickered slowly again.
Does anyone know what is going on and what sort of driver is necessary? We're banging our heads against the wall here
