Ha! They're catching on to all those KL4 1W and 3W "downgrade" mods. Glad to see it happen. And that 2-stage dimmer, they need to make the dim mode regulated and not dump all that current into a resistor like the L1 and A2 does.
As far as trends, I think it's more away from the 1W and more towards the 3W. Hopefully, Lumiled's will figure out how to fix the "portable" 5W so that they can rate them for more than 500-1000 hours.
