The Acute2 head is fan cooled and it has an automatic voltage 

selector for the fan. The dimmer controlled modelling light is 

powered directly from the mains and it is therefore important 

to check that the rated voltage for the lamp corresponds with 

the mains supply. A 250 W E11 Mini-can halogen lamp is 

included in standard deliveries. The Acute2 head is supplied 

with a frosted UV-coated glass cover and a Zoom reflector. 

Combined with the UV-reducing quartz flash tube the frost-

ed glass cover offers the recommended colour temperature 

for daylight type film. Distinctive colour temperature adjust-

ments can be obtained by combining glass covers with differ-

ent coatings. The following glass covers are available:

10 15 33        Glass Cover, frosted, UV-coated (standard)

10 15 35        Glass Cover, frosted, extra UV-coated, -300°K

10 15 34        Glass Cover, frosted, uncoated

10 15 37        Glass Cover, clear, UV-coated

10 15 39        Glass Cover, clear, extra UV-coated, -600°K
