It's the cost of assembling a compact voltage reg that can cope with 10.5 to 15 volts, surely? All the best Bruce I have been using one of these for about a year. see http://www.yourwelcome.co.uk/acatalog/LED___12v_MR16.html It does run on the transformer that powered the 12 Volt 20 W filament version. The light output is very good for 3 watts 12 V What we could do with is someone to try one to see if the battery voltage swings damages one!
