thank you for all the responses. I had a 20% off postcard in the mail today from competitive cyclist, which I take as a sign that I should buy a light, but they do not carry the six pack, only the smaller brother MaXx-D. This is rated for 2400 lumens which is only double my Diablo.

I'm concerned that these lights will not properly light the road without blinding drivers, rendering it a downgrade from my Diablo. Any guesses on that situation?
