The Bright Sun FLOOD was developed as alternative to metal halide flood lamps and ensure a large scale illumination of the terrarium thanks to a 70 reflector. The lamps offer UVA and UVB radiation as well as a certain heat output. For best illumination of your terrarium we recommend a combination with a Bright Sun UV Desert to create local sun spots. For animals with low UV requirement like geckos the Bright Sun FLOOD may be used as sole lighting. Ballast necessary!
