To address market requirements for LED lamps that more closely approximate the characteristics of halogen lighting, Verbatim will launch a new range of LED products based on Seoul Semiconductor (SSC)’s ‘nPola’ technology.

‘nPola’ uses gallium nitride (GaN) substrates from Verbatim’s parent company Mitsubishi Chemical Corporation for GaN epitaxial growth, replacing sapphire or silicon carbide substrates. Seoul Semiconductor’s patented nPola minimises defects in the active layer and allows LED chip current densities 5 to 10 times higher than conventional chips.

Consequently, 5 to 10 times brighter light output can be realized from the same chip size. Verbatim’s initial launch of nPola halogen LED lamps will focus on the MR16 form factors, with a primary target of 50W MR16 halogen equivalency.

The combination of high light output and beam characteristics that closely resemble halogen lamps will allow lighting designers and contractors to
adequately replace halogen lighting with high performance, energy effi cient LED products in both new design and retrofit environments.

One of the distinct advantages of GaN on GaN Technology is the realisation of a singlecore LED, which can prevent the multi-shadow phenomenon common to multi-core LED lamps.

Such sharp and clear shadow effects would be ideally suited to commercial applications such as jewellery and interior goods store displays.
