Our History


Since the incorporation of Lightning Down Under (LDU) in 1999, we have experienced a continued expansion. LDU has grown from being a distributor of surge protection product to designing and manufacturing our own unique protection solutions. We simply looked at what was on the market and improved on it while developing solutions for other niche applications.


In 2002 we became the Australasian distributor for the Prevectron Early Streamer Emission terminal manufactured by Indelec, France. The Prevectron is the only true ESE system available today with considerable real life, in field testing using actual lightning, conducted over the past 40 years and into the foreseeable future with a new testing facility being located in Indonesia. Since then we have installed over 500 systems throughout Australia with an enviable success rate in protection against direct lightning strikes. Indelec have installed over 250,000 systems throughout the world.


In 2003 we moved into a larger premises in McGraths Hill NSW. This allowed us to increase our capability for research and design, and our capacity for manufacturing.


In mid 2003 we incorporated LDU Consultants Pty Ltd which is charted with the responsibility to design lightning protection and earthing/grounding solutions and to offer advice in the areas of lightning, surge protection and earthing.

In mid 2004 we released the first of our own LDU range, the EMOV Surge Diverter. At the end of 2007 we released our EDIN range of diverters. During 2008 we  developed and released a new range of surge protection under the Gatekeeper brand as well as earthing product, to add to our stable. Further we have a full range of high quality UPS’s to further enhance our turnkey solution approach.


We have spared no expense to ensure the LDU range of surge protection is of the highest quality and reliability. Our product is now available throughout Australia. During 2012/13, our product will become available throughout New Zealand and the South Pacific. In 2012 we ventured further into the export market.


During the last 26 years, I have been witness to an evolution in the industry. Once it was thought that lightning and surge protection was black magic or mystical in nature. This is a diminishing point of view, as the market gradually understands that lightning and surge protection is based purely on solid, well-grounded science. We believe the industry is maturing, developing the requirement for good quality reliable protection combined with excellent customer service.


At LDU, we endeavor to supply turnkey solutions, which are both technically and economically effective. We are always looking at ways to improve both our product and service. By accomplishing this, we can keep our cost low and therefore our price to our customers low while keeping our high standard of customer service.


We are proud to be 100% Australian owned and operated, and it is this pride that will ensure that we remain Australian supplying high quality, reliable economical Australian solutions to our customer’s problems. Combining our 26 years experience in providing solutions for lightning and over-voltage issues with our firm commitment to honesty, integrity, loyalty and total customer service, LDU is well placed to address any problems, which may arise and to service markets located throughout Australia and South East Asia.
