Soraa launches first high-color-rendering, line voltage MR16 GU10 120V LED lamps

Soraa Inc of Fremont, CA, USA, which develops solid-state lighting technology built on ‘GaN on GaN’ (gallium nitride on gallium nitride) substrates, has launched what it claims is the first line of high-color-rendering LED MR16 GU10 120V line voltage lamps.

Uniquely, the firm has released a 10o spot version (not available in halogen or from other LED makers, it is claimed) as well as a 25o version that has a center-beam candle power higher than halogen and all other LED GU10 products on the market. Transformer-free, full-visible-spectrum Soraa LED lamps are now available that render the widest range of colors in the objects that we see, without ultraviolet (UV) or infrared (IR) radiation, claims the firm.

The LEDs also offer full dimmability, long lamp life, improved energy efficiency and compatibility, says Soraa. “All these features are made possible through our proprietary GaN-on-GaN technology,” notes president & chief operating officer Tom Caulfield. “With our GU10 versions, you no longer need a transformer and we have made available beam and output options that did not previously exist in the market, because of limitations with all other technologies.”

The firm’s continuous full-visible-spectrum GaN-on-GaN LED MR16 lamps, with a color rendering index (CRI) of 95 and R9 of 95, render deep reds and cyans dramatically and have no spectral ‘blue-peak’. Also, like natural light, Soraa’s lamps contain violet light, which excites optical brightening agents present in fabrics and fibers and renders whites truly, the firm adds. The lamps exceed the color metrics of other LED lamps, without the manipulation of spectra that are commonly seen in other manufacturer’s products, it is claimed.

The GaN-on-GaN LEDs emit ten times more light per unit area of LED material than LEDs built on lower-quality foreign substrates, Soraa reckons. Its lamps hence have a single light source that casts a perfect beam and a single clear shadow, bringing out textures and contrast.

Making Soraa's light available in a GU10 base solves problems for users such as transformer compatibility, says lighting designer and author Randall Whitehead. “It also makes it easier to install in homes, reducing overall installation and fixturing costs,” he adds.

The new MR16 GU10 lamps are compatible with a wide range of dimmers, which Soraa has tested and characterized through its Works with Soraa program. Also, the firm’s heatsink design and thermal management system make its lamps suitable for use in enclosed fixtures, damp locations and outdoor applications.

The new MR16 GU10 10o lamp works with Soraa’s magnetic attachment SNAP System. The Premium 2 10o version of the lamp has a center-beam candle power of 7120Cd and the 25o version has a center-beam candle power of 2140Cd — twice that of halogen, it is reckoned.
