Being a big fan of Fresnel lenses I was eager to relamp with this old stage lamp with an LED source. While the CXA2011 isn’t the newest package it was handy. A future upgrade to the 25XX might be in order in the near future. Pushing it to 700mA required active heat sinking on account of the enclosed space so I utilized a Synjet. The output is a very pleasant 3000K semi spot through the lens. The last picture is of the phosphor on the chip being excited by a royal blue light source outside of the lamp, the result is a faint orange glow.
