Designed and manufactured here in the uk by a leading effects lighting company that started in the 1960s to create light shows for bands such as pink floyd, cream and the who, they then turned their expertise into projectors for the disco, retail, exhibition, and therapy markets. The opti aura projector lamp uses the first ever effect that they produced using a 6 coloured wheel that produces a projected effect of vibrant globules of coloured light, an effect which is still as mesmerising and in demand today. The aura sensory projector is suitable for all, whether as a home projector to create hypnotic and cool effects for parties, as a soothing light for spas and therapists, or as a great cost effective light for a home snoezelen or sensory rooms. The opti lamp can project a moving image of any size. For best results use the projector in a dark room projected onto a light coloured surface. The aura sensory projector has a simple plug and play operation and can be turned on and off, dimmed, and set to 30 minute timer mode from the unit itself, making it a fantastic night light too. One standard multi coloured wheel is included, and additional colour wheels are available, however these are sold separately. Rainbow dream awakens your senses in a soothing mix of primary colours as red, blue and yellow gradually slide together into soft, mysterious shapes in a mesmerising motion that allows anxiety to melt away. Bright and bold, pink lady has a depth of colour produced using passionate pinks, violets and blues creating imagery that's both thought provoking and stimulating, and is guaranteed to captivate your imagination!
