The AriesX 150W Modelling Lamp is mostly used by photo studios as a modelling lamp for photographic lights and in order to see where the light falls onto a subject. It is a frosted double envelope bulb designed primarily for strobes. The medium screw base fits most monolight strobes and fixtures. 

The double envelope design is made to protect the actual lighting element of the bulb from contaminates. The frosted glass exterior provides a softer glow, distributing an even and pleasing light onto the subject. The bulb is also mercury free and does not require any special disposal. It has an average life of 2000 hours.
