Founded in 2008 by Raimar Geffken, a German entrepreneur and lighting professional, we thrive to provide lighting solutions that support human well being and productivity. We work along with renowned international brands that complement our own range of solutions that earned the merits of being branded Ralum.

Ralum is incorporated in Jakarta, Sydney an Singapore and has completed projects in various countries.  

As we grew up in a truly challenging market, we have been duly strengthened in our creative approach to find unique solutions and "make things happen". As a result, we are well set to take on all challenges along the way of implementing a project - always - ready to go that extra mile!

We work in a small, qualified and motivated team along with a network of long-term professional partners for manufacturing, supplies, logistics, installations and other services. 

Our core believe is in "bringing good lighting to the people".  Long-term business relations and being of value to our stakeholders and society are more important to us then quick gains. We believe in growth through creativity, not competition.
