I'm awaiting the few I've had on order, hopefully they'll be here soon. Though I haven't gotten any specs yet here are a couple of things to be aware of:

- The KL4/5/6 LED's will have a blinding capability well over 10' but won't really equal the performance of a P60 lamp at longer distances.

- Peak output runtime with the 5 watt LED's is probably only going to be marginally better than a std. incandescent P60.  The L4 5 watt has a basic runtime of approx. 70 min. at peak performance BUT when it drops off it won't leave you in dark, you'll still have minimal light output for a lengthy period.

- I'm suspecting that the KL5 & KL6 will basically have equal light output and that the major difference will only be runtime.  If you'll notice the KL3 performance specs don't really change as far as Lumens output when comparing it on a 6v & 9v system.

Forest, I'll know more after the first of January but to be honest, I'm not sure if I can make things come together like I'd need to.
