Looks like roithner-laser are using Lamina boards with their own ( or some other )chips with much better efficiency (40Lm/W) other than Lamina's (23Lm/W). /ubbthreads/images/graemlins/grin.gif
The 7-cavity array from Lamina is rated at 108 lumens @ 4.7W typical ( no maximum is stated )whilst roithner ones are rated at a whopping 840 lumens @ 21W max. /ubbthreads/images/graemlins/smirk.gif
that's more than 8 times the flux at less than 5 times the power.
They also have a 134 cavity array delivering a massive 5360 lumens @ 134W max
Now i don't know if these figures are obtained from running it in some cryogenic bath or something but that's bloddy bright for a LED device.
Although there is very little info for the 134 cavity one and it is not for sale yet, the 7 cavity one is, for 115.85$ for 1-9pcs.
compared to the 18.15$ for the lamina one that's F@#%$* expensive but it's 6 times the price for 8 times the light which sounds like a good deal to me.
Oh it's also flashlight friendly (apart from the optics bit)since it runs at 4V not 11.3V like Lamina.
