Product Description

Arthur LT is a new Long-Throw adaptation of the original Arthur followspot with a narrower beam. Featuring a zoom range of 4° - 10°, Arthur LT provides an output that exceeds an HMI 2500W Aramis. The LT version ensures invincible performances with an output of 2000 lux at a distance of 50m (200fc at 165 ft), while offering an enhanced light quality with a high CRI (>94) - an essential feature for a followspot whose main role is to shine a light on performers and showcase them in sublime fashion. With the choice of several ventilation modes, Arthur’s sound level is much quieter than any of its discharge rivals; it can be operated as easily in opera houses as on concerts and big arenas.
