LED Lamps have solid-state reliability. They are rated up to 200,000 hours of use without glass bulbs to break or filaments to burn out. They are extremely energy efficiency, using only 10% of the electricity required to power traditional incandescent bulbs. They are indestructible, are cool to the touch and do not require any transformers. They use your standard 120 volt house power.

*** rf-plasma-assisted MBE growth of MQD GaN/AlGaN UV LEDs *** 3 samples, Al-content in p-AlGaN cladding layer varied (8.8%, 13.1%, 25.1%) *** p-cladding layer coalescent (550 nm) *** height of NW 900 nm, diameter 100 nm *** EL measurements, peak at 354 nm (50 mA, RT) *** FWHM 200 meV (25.1% Al) and 300 meV (others) *** light vs. output (dc and pulsed), up to 300 mA, peak at 353.1 nm for pulsed *** peak shift due to heat generation, thus 40°C/W thermal resistance
