Introducing the compact LED engine and driver that is ideal for convenient retrofitting of conventional MR16 luminaires
.

Even today, MR16 fixtures can still be found in many hotels, bars and restaurants, retail shops as well as offices and hospitals. They have been the light source of choice for many years – but those who are conscious of energy cost and the importance of sustainable practices in today’s modern world are relying on cutting-edge, durable, LED lighting technology.

If you want to retrofit old MR16 luminaires with little effort and in no time at all, OPTOTRONIC FIT 8/18 CS PC and PrevaLED COIN 50 CoB from OSRAM are ideal for you. This forward-looking solution consists of the compact, dimmable LED driver, which seamlessly integrates into the existing luminaire architecture, even where there are space constraints, and a cylindrical LED module which can be installed with just a few simple steps to replace an obsolete MR16 halogen spotlight.
And its not just in retrofit situations where the PrevaLED COIN is useful. There are many installations that still use the MR16 form factor. These projects tend to utilise discreet downlights originally designed for a tungsten halogen MR16 lamp but now fitted with an LED equivalent. These are often small to medium budget schemes but there is now no reason to compromise on light and colour quality.
At a glance, the PrevaLED COIN offers
- Consistent white light: < 3 SDCM
- Color rendering index Ra: >80 and >90
- Luminous flux: 980…1,500 lm (model dependent)
- Beam angle: 15° (on demand), 24°, 40°
- Max. working voltage: 60 V (to be operated only on SELV LED control gear)

A compact and powerful mains-dimmable LED driver
This compact LED driver offer a number of attractive advantages. The abbreviation “PC” in the product name OPTOTRONIC FIT 8/18 CS PC stands for “phase-cut”, i.e. for leading- and trailing-edge dimming in the 100 to 5 % range. The low ripple current provides for superior lighting quality, and flexible current setting via a DIP switch ensures superior functionality (i.e. no programming and no resistor required and with a large selection of output currents from 100 to 450 mA). OPTOTRONIC FIT 8/18 CS PC are available with plug-in or screw terminals for both integration into luminaires and stand-alone installation.
