International Patent N° WO 2013/024501 A1
Advanced Optics for LED Projector with FRESNEL or PLANAR-CONVEX Lens
ENERGY SAVINGS:
The Energy Savings introduced by this products are remarkable. The following table shows a
Comparison of the energy conversion for both Tungsten and Daylight Super LED F4.7 when
compared respectively to a 750 W Tungsten Fresnel and outperforms a 250W HMI, which are
the equivalent lighting performance conventional fixtures, when analysing the output beam
from middle to full flood:

The DE SISTI LED FRESNELS Tungsten are:
- 100% Dimmable locally or via DMX with super smooth dimming dynamics
- No separate DIMMERS required (No Dimmer Room and Simpler Cabling system)
- All self contained in the Luminaire housing (no separate ballasts or power supply)
- Power and DMX Daysy chain able
- High energy savings when compared to Tungsten Fixtures with negligible POWER REQUIREMENTS
and very low Thermal Emission for contained cooling systems in the studio.
- Extremely contained Maintenance (mostly cleaning): no lamps replacement
The DE SISTI LED FRESNELS Daylight are:
- much less expensive then equivalent HMIs fixtures
. They are 100% Dimmable locally or via DMX with super smooth dimming dynamics
- All self contained in the Luminaire housing (no separate ballasts or power supply)
- Power and DMX Daysy chain able
- Yet introduce significant energy savings when compared to HMIs
- Extremely contained Maintenance (mostly cleaning): no expensive lamps replacement
