I live in Sweden (country with severe darkness) and just bought two Virtual Sun united from https://innerscene.com/
NOTE: Be extremely careful when transporting/moving these units, they easily break. The supplier who imported them on my behalf got two shipments with broken units until they finally got one that wasn't damaged. This happened despite FRAGILE markings on the packaging.
Innerscene's Virtual Sun is much smaller and lighter than the classic Coelux.
Coelux:
Weight: 300 kg (660 lb)
Dimensions: 2375 x 1675 x 691 mm (93.5 x 65.9 x 27.2")
Innerscene Virtual Sun:
Weight: 39 kg (85.8 lbs)
Dimensions: 1001 x 514 x 255 mm (39 7/16 x 20 1/4 x 10")
