RLOD#11 (2020.05.15) 2010 GE MVR250/C/U

The MVR250/C/U shown here is representative of the last generation of fluorescent metal halide discharge lamp produced by General Electric in the USA. Typical of standard American metal halide lamps intended for general lighting applications, this model has a sodium-scandium iodide fill chemistry that delivers a high initial light output with a reasonably good light color quality. Its fluorescent coating, consisting of a standard red-emitting europium-activated yttrium vanadate material, reduces glare, lowers the light color temperature by 300 K to 3900 K, and raises the light color rendering by 5 points to 70 Ra8, thus making it an ideal source of intensive indoors lighting. Interestingly, this MVR250/C/U features a unique bulb shape with a conical neck section, which was most likely introduced in order to facilitate the automated production of the lamp at high speed. This shape enables a better, more consistent seating of the bulb on the rotating heads of sealing machines, thus resulting in a more precise alignment during assembly.
