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! ETA August 2008
