4-tube LED panel using new state-of-the-art 24" linear LED tubes. Provides higher CRI than with 5mm LEDs & emits a softer, wrap-around light that suits studio use. Also works superbly as a portraiture light source for photographic applications where the harder pulse of a flash unit is less desirable such as new-born & young children portraiture, pet photography & heat-sensitive subjects such as food. Fully compatible with the accessories currently available for our SL455DMX fluorescent Studiolite too.
