My first Tigerlight lamp had bat wings but was still impressive. My 2nd lamp had no bat wings, a fairly well defined central spot with amorphous corona, and was very impressive in terms of brightness, throw and total useful beam diameter.
Randy Teig's evident goal was to combine the features of a very bright, long throw, wide-beamed light in a relatively small and light weight body. He succeeded, up to a point, but problems gradually surfaced: inconsistant performance from lamp to lamp, premature yellowing, varying beam patterns. Supposedly the problems lay with manufacturing rather than with design, and Tigerlight was having problems maintaining adequate quality control. At least this is my impression from reading posts from Randy along with comments on CPF.
The situation remains confused and has never been clarified to most people's satisfaction. Tigerlight was pushing the envelope with this light and IMO a quick resolution of these issues is not assured.
At its best the Tigerlight is a remarkable, even unique light. My hope is that the company will eventually achieve the consistancy necessary to satisfy old customers and inspire confidence in new ones.
