Transformerless LED lamps with light emission up to 50 lumen per watt
Soraa has made available halogen lamps replacing LED lamps with light emission efficiency up to 50 lumen per watt. These LED lamps can be powered directly from 120V main supply voltage without requirement of transformer. Another specialty is they said to render high color. The MR16 GU10 is a 10º spot version and 25º version. Even though they emitt broad spectrum of visible light but not the ultraviolet (UV) or infrared (IR) radiation, as per Soraa. These LED lamps are useful for beam lights.
Soraa has used what it calls Gallium Nitride (GaN) on GaN technology to make the LED defect free and emitt more light/watt compared to other technologies in the market.
Soraa says its LED MR16 lamps, with a CRI of 95 and R9 of 95, render deep reds and cyans dramatically and have no spectral “blue-peak”. And just like natural light, Soraa’s lamps contain violet light, which excites optical brightening agents present in fabrics and fibers and renders whites truly.
MR16 GU10 lamps are compatible with wide range of dimmers and Soraa has used novel heatsink design and thermal management system make their lamps suitable for use in enclosed fixtures, damp locations and outdoor applications.
Soraa’s new MR16 GU10 10º lamp works with the company’s innovative magnetic attachment SNAP System, and the Premium 2 10º version of the lamp has a center beam candle power of 7120Cd and the 25º has 2140Cd—twice that of halogen, as per Soraa.
If you'd like to know what is the highest lumens per watt presently achieved by LED manufacturers, Philips has created white LED lamp with 200 lumens-per-watt and Cree has reported R&D performance of 276 Lumen-Per-Watt Power LED. Cree's MK-R LED which is already released in the market delivers up to 200 lumens-per-watt.
