What would you recommend MateThat all depends on the holder you purchase
First it has to be bird specific
If it's a round holder shaped rather like a lampshade then your not going to get much out put for the bird.
Length of bulb if it is a lampshade shape has an issue as some bulbs are longer than others
Also remember you have to find out it it's a screw or bayonet fitment inside the holder as that will give you certain selections.
Ceramic reflectors are mainly for heat bulbs and lighting specifications for reptiles and amphibians not birds reptiles / amphibians have different spectrum requirements.
