L6 runtime _____few pics added

[FC.]

I have conducted a side-by-side run-time test on L4,L5,L6

1hr - all are bright
65 minutes - L4 is out, L5,L6 still going
69 minutes - L4,L5 are out, L6 still 100%
90 minutes - L6 still 100%
95 minutes - L6 at 100%
110 minutes - L6 at 100%
115 minutes - L6 at 90%
120 minutes - L6 at 60-70%
125 minutes - L6 at 40-50%
130 minutes - L6 at 25%

Conclusion: you can get 1hr45 minutes 100% output out of L6.

Re: L6 runtime

Heat.
After 1 hr you can not touch L4, L5 is very hot, L6 is barely warm(like KL1 after 1 hr).

sounds good for the L6 ... cool!

Re: L6 runtime

Just looked at my L5,L6 boxes

L5 - "Long Runtime"
L6 - "Super-Long Runtime"

Re: L6 runtime

Double the runtime, 3x the brightness, 1.5x the batteries. That's good math for me!

This is definitely one reason to "warm" to the L6.

Thanks, FC.

Cheers,

Richard

Re: L6 runtime

FC, thanks for the runtime test. Did the L6 get too hot at the end of its regulated output? The longest I have used mine for is 10mins, and it barely gets warm.

Re: L6 runtime

Noup. Stays warm, never hot.

Re: L6 runtime

What about comparison beamshots?Thanx!

Re: L6 runtime

OK. Too cold to go outside, so I shall take inside pictures.

rlhess- 3x the brightness, >>>>>>>>>>>>>>>>>>>>

Where do you get these figures ? I don't see it, unless you're talking about a slightly smaller hot spot (more Lux/candela))

I see the same 5 watt with a different reflector.

Re: L6 runtime

OK, John, 2.5x the brightness...in the center.

I was referring to throw brightness, not total light output. They both have approximately the same total light output, although the L6 may have a hair more as it appears to possibly be driving the LED 10-20% harder.

Measurements are about 650cd for the L4 and 1600cd for the L6 at beam center.

The throw of this light is obvious at my light shootout. I didn't have an L5.

Cheers,

Richard

Re: L6 runtime

Great shots FC! I really like the baseboard shots, you seem really good at it. /ubbthreads/images/graemlins/rolleyes.gif /ubbthreads/images/graemlins/whoopin.gif /ubbthreads/images/graemlins/grin.gif

The L6 does look brighter.
Thanks for doing a run-time test. I was hoping for 2 hours run-time from the L6, it looks like it comes really close!

Re: L6 runtime

Great stuff, thanks lots FC! Oh, and great pics too... I barely noticed the E1e/KL1 beam if not for the pic of all the lights together. Think the light output from all the other 3 sorta 'overwhelmed' the output from the E1e/KL1... Thanks again! /ubbthreads/images/graemlins/thumbsup.gif

Richard,

In your earlier chart (Candela/Throw for 1 fc/typical light), you had the KL5 listed at 2000 candela; does this mean the L6 has less candela than the L5??

Thanks!

Re: L6 runtime

FC,

Nice shots! I especially like the final shot of the lights bezel down; not so much for the information conveyed but simply for the artistic composition. It's very effective and appealing to me.

Re: L6 runtime

Measurement techniques and individual light samples vary and yes, it does mean that my measurement technique and my sample of the L6 has a lower peak output than the other person's L5 based on his measurement technique.

I'd love to see Quickbeam's comparisons.

Cheers,

Richard

Only a flashaholic would know what these are... /ubbthreads/images/graemlins/grin.gif

Great shots!

Re: L6 runtime

Yes Don, I like YOUR pictures also.
