We have a veiled and just bought a dual fluorescent linear bulb hood from dyi cages (they are sponsors of this site). the link below might help you find the right lighting...we bought a repti glo 2.0 and 10.0 for the 2 bulb hood.
1 linear tube reptisun 5.0 uvb(needed for groeth and development for most chams including veileds)
1 regular hardware house bulb for heat with a lamp fixture...watts between 60-75 watts(depends on the temps you get)
temp should be 80-85 for babies and juveniles and adults about 88 degrees for highest temp the rest of the cage should go down to 70-75,....at night as low as 65 degrees..
yeah you'll definitely need a basking lamp too...forgot to mention that.
how big is your cage? we had the 5.0 first but our cage is 24x24x48 and feel that is was not enough which is why we got the dual hood with both lamps. Keep in mind that the mesh reduces the strength of the light by 50%.
