From 13 April 2015 mercury vapor lamps will no longer be manufactured in Europe following the European Directive 245/2009.
This regulation puts an end to sources with a very average output of 50Lumens / Watt and with a very low color rendering index or RA of 50. However nothing prevents manufacturers or resellers from selling their stocks after this date . The mercury vapor bulb is the least efficient of the discharge lamps, with the potential to reduce energy savings by up to 75% if all the fixtures were replaced.
In France, it is estimated that 40% of the total number of public lighting fixtures in service is more than 25 years old and one third are equipped with mercury vapor lamps, not to mention public or private indoor facilities such as hangar lighting Or the industrial park, estimated at more than 3 million units.
The lighting manufacturers advise to replace the complete luminaire either with a metal halide version or with a less energy-consuming and more efficient LED version listed on carswers.com.
However, these lamps can be substituted by so-called “retrofit” sources (direct replacement without modification of the equipment) by metal halide lamps such as RELUMINA from Sylvania .
Relumina is a metal halide lamp with a yield of up to 88 Lumens / Watt, with an IRC of 84 which is directly replaceable instead of the mercury vapor lamp equipped with a ballast:
55w to replace 80w
85w to replace 125w
170w to replace 250w
This solution is a short-term vision because the integral replacement of the luminaire will remain the best investment in saving up to 75% of energy.
