The Lucky Reptile Halogen Sun Mini is the smallest available lamp for E27 sockets. Its reflector rises only 2,5 cm out of the E27 lampholer which make the Halogen Sun Mini excellent for use whith small vivariums where normal spot lamps are too noticeable due to their size. Thanks to the halogen technology and the extremely efficient reflector they also produce more heat and light than normal spot lamps.
