This was a custom build for a customer looking for a variable output flood lamp to be used with a small solar panel and battery system. The Cree CXA1507 (3000K) package is driven by a boost puck with a max output of 350mA but tuned down to 200mA for reduced power consumption and better thermal performance (case temp of about 30c) . While this was just a prototype the final version was to be water resistant using some type of gasket around the lens. Future builds of this lamp will most likely not be machined from a single block of aluminum. The anodizing is HA type 3 and mostly likely overkill for this application but it adds a nice touch. A standard bolt hole (1/4-20) was added for versatility in mounting.
