The myths sur­round­ing industrial LED light­ing

DEMM Engineering & Manufacturing - - LIGHTING -

Ac­cord­ing to Con­sult­ing-Spec­i­fy­ing En­gi­neer­ing Mag­a­zine, there are six myths that need to be de­bunked in re­gards to LED light­ing.

The first is that LEDs are not a cost-ef­fec­tive re­place­ment for f lu­o­res­cents. How­ever, although the ini­tial setup can be pricey, LED soon starts pay­ing for it­self, with the ma­jor­ity of busi­nesses mak­ing dra­matic sav­ings.

Some say LED tech­nol­ogy is too new to have proved it­self but the prod­uct has been used for well over a decade now, in­clud­ing in crit­i­cal safety-re­lated ap­pli­ca­tions.

The next myth is that LEDs have mag­netic bal­lasts that re­quire ser­vic­ing and/or re­place­ment. Not so, says C-SEM, LED lights use elec­tronic driv­ers, which don’t need re­place­ment.

But, say the de­trac­tors, prices will go down, so it pays to wait. Maybe so, says the mag­a­zine but wait­ing for those fix­tures to drop is go­ing to cost you money in the mean­time. And the en­ergy sav­ings from up­grad­ing a fa­cil­ity’s light­ing to LEDs far ex­ceeds any in­cre­men­tal price de­clines in LED-based fix­tures.

There is still some doubt about how well LEDs work in high­tem­per­a­ture en­vi­ron­ments but tem­per­a­ture tests con­ducted by in­de­pen­dent labs, show LEDs per­form at least equally as well as f lu­o­res­cents and HID and also per­form ‘ex­traor­di­nar­ily well’ in cold en­vi­ron­ments, an area that has been par­tic­u­larly chal­leng­ing for other types of light­ing, such as f lu­o­res­cent and HID. And fi­nally back to that hoary old chest­nut that com­plains that the ex­tra in­vest­ment for in­tel­li­gent LEDs doesn’t re­sult in pay­back. Just wrong, wrong, wrong says C-SEM. Sen­sors em­bed­ded in in­tel­li­gent LED lights pro­vide op­por­tu­ni­ties for mas­sive sav­ings.
