I don't need one but bear in mind that since it's for medical use it can NOT be bright since you are supposed to shine it in people's pupils to check for correct response. If you use a blindingly bright light it's not helpful. The first light i was going to use was rejected by my director as too bright.

OldManTickHonestly, that's kind of not true. If you know how to use a light, any flashlight made can be use for pupil response. You can dead-angle a bright light and only barely graze the corner of the pupil without any real discomfort - I find it works better anyways than a flat "shine straight in the eye" because oftentimes the straight shot with a penlight technique doesn't cause a rapid enough change in pupil size for many people to be diagnostically relevant - particularly if you're not in ideal light to start with.
