4.5W LED 12V MR16 istoria 6000K 4.5W LED 12V MR16 istoria 2700K

At the Energy Solutions Expo October 2011, IstoriaLED very generously gave me a couple of review samples (one warm/2700K+, one cool/6000K+). Both have an A+ energy rating, are 4.5W and 351lm (650 eff lm) and 50000h life. Initial subjective testing suggests that the cool light is nearly as bright as my 720lm/7W Aurora V5.

The cool seems much brighter than the warm (I expect some difference, but not this much).

I'm a big fan of these and work by the "cool" lamp at my desk instead of the 7W mains EQ60 as of 2012 sometimes to be completely 'off-grid' for lighting.

I've lent both the "warm" and "cool" lamps to a friend (MF) considering replacing 12V MR16 halogens in his bathroom for energy efficiency reasons, and once he'd overcome some transformer trouble (not liking the very low load that these lamps present cf halogens) declared that he would be happy with either colour and that the light volume was good for his purposes.
