White Led driver

The circuit below can be modified to drive up to 30 white LEDs.  The effectiveness of a LED array increases when they are spread out slightly and this makes them more efficient than a single 1 watt or 2 watt LED.  The two modifications to the circuit make the BC337 work harder and this is the limit of the inductor.  The current consumption is about 95mA.  The winding details for the transformer are shown above.
