As led lighting applications are
oversupplied in the market, it’s tougher for customers to choose led
lighting suppliers which are reliable. Not all claims manufacturers make are true. Los
Angeles tests new LED fixtures every six months. Manufacturers interested in
selling LED fixtures to the city can submit products for testing at the Bureau
of Street Lighting website. City specifications are revised based on testing
results and technology improvement.
These improvements, coupled with
falling production costs, have yielded a reduction in per unit cost. At the
time of Ebrahimian’s Miami presentation, September 2012, the per unit cost was
$309 (85% materials, 10% engineering, and 5% labor); when Ebrahimian delivered
his talk in Los Angeles six months before, the per unit cost was $495.33.
So far, manufacturers have
requested evaluation of 244 LED units; 84 met the minimum requirements; 71 were
installed and tested; and 20 units were approved for use. Approved LED fixtures
for so-called “cobra head” street lights include: Cree’s XSP series and LEDway
series, Hadco’s RX series (Hadco is a Philips company), and Leotek’s GC series.
In a word, when you want to buy Led
garden lights or other applications, it’s important to find a reliable and true led
lights manufacturer, which matters not only on the service, but also the
products.
