These reliable and energy-efficient based LED lamps are ideal as drop-in replacements for existing less efficient incandescent or compact fluorescent (CFL) indicator lighting products. Based LED lamps offer an extremely long lifetime (typically 100,000 hours), low power consumption, low heat generation, and excellent shock and vibration resistance, Their long service life reduces the total cost of ownership and their high reliability makes the product line ideal for critical applications where the presence of indication is essential or where lamp replacement is difficult or costly. 

The APEM range of based LEDs is available in several options, including high intensity single-chip LED, cluster, and multi-chip versions. Integral resistors allow direct connection from 6V through 230V, depending upon the model selected.
