A first device that may include one or more organic light emitting devices. At least 65 percent of the photons emitted by the organic light emitting devices are emitted from an organic phosphorescent emitting material. An outcoupling enhancer is optically coupled to each organic light emitting device. In one embodiment, the light panel is not attached to a heat management structure. In one embodiment, the light panel is capable of exhibiting less than a 10 degree C rise in junction temperature when operated at a luminous emittance of 9,000 lm/m2 without the use of heat management structures, regardless of whether the light panel is actually attached to a heat management structure or not. The light panel may be attached to a heat management structure. The light panel may be not attached to a heat management structure.
