Juwel HeliaLux Spectrum 1000 is a 48 W LED insert, 993 mm long. White LEDs give a clear light, while red, blue and green LEDs bring out contrast and colour.

It is a full-spectrum light for planted aquariums and uses about half the energy of older fluorescent tubes of the same length. Dimming is done with the Juwel SmartControl, sold separately.
