The Viva is new LED light from Giesemann which inherits much of the styling and design of the Vervve but in a new form factor and power level. Where the Vervve LED is designed to be Giesemann’s hot rod LED light, the Viva was developed to be a more cost effective LED light which blurs the line between a module and a full length aquarium light fixture.
To build the Viva, Giesemann started with the same LED lens cluster as the Vervve. But where the Giesemann Vervve has a maximum power of 185 watts across two clusters of LEDs, the Viva has a total power of 150 watts spread across three different clusters. So instead of having a pair of active cooling fans, the Viva’s larger size and therefore greater heatsink area allows it to passively and silently dissipate the heat from the LEDs.
Also, rather than make a whole suite of different Viva LED fixtures, Giesemann opted instead to build just one size of the Viva light, a 90 cm (36 inch) fixture which is ideal for tanks up to four feet long, or 120cm. The Giesemann Viva still retains individually controllable LED color channels, wireless programmability as well as a couple different mounting options.
The Giesemann Viva showed off at InterZoo was just a prototype, but we found the combination of the matte black heat sink and glossy white side fins of the light to make for a very attractive light fixture. Hopefully we’ll get to see this light running in the enar future and we expect full release details and pricing to be announced by the time MACNA rolls around.
