Why doesn’t Lumitec have any published Lumen information?
a. Our research indicates that lumen data as published by many lighting suppliers is grossly inaccurate, or at best misleading. To accurately ascertain this information one needs to conduct careful testing using sophisticated equipment. In lieu of this, many companies generate lumen ‘approximations’ by simply adding the lumen output published by emitter manufacturers. Unfortunately, this data usually yields approximations which are significantly overstated. The reason is that the initial emitter output data is generated in a laboratory, with a junction temp of 25C, at a pulse of about 20 mS. This emitter lumen output information is really only useful for comparing one emitter to another. Moreover, this ‘hypothetical’ lumen data is typically not derated for reduction of luminous efficiency due to heat, optics, windows, elevated drive currents, etc. Naturally, it is not our policy to knowingly publish incorrect information. Therefore, we prefer to compare our lights to alternate light so
