I browsed the new Maplin (UK) catalogue today and saw some 1W LEDs in a
TO 220 package. For the uninitiated these are the same package used for
many high power transistors, triacs, voltage regulators and other stuff,
and look like a small rectangle with a heatsink tab on one end and two
or three legs sticking out the other.
I suppose this makes sense since it facilitates easy fixing to a
standard heatsink with a wide range of standard insulating shims and
screw isolators to ensure isolation from the heatsink. I can imagine
these being ideal for use in long strips where a thin PCB runs under the
legs making connection. It should allow quite dense linear packing if
the heatsink is up to the job.
