HID lamp is high intensity discharge lamp. High pressure sodium lamp, high pressure mercury lamp, xenon lamp, metal halide lamp are all belong to HID lamp.
We generally use Integrating Sphere Spectroradiometer Test System to test the photometric, colorimetric and electrometric parameters. Generally we suggest the diameter size of Integrating Sphere according to the size of lamp under test. If you test single LED or LED chips, we recommend small integrating sphere such as IS-0.3M or IS-0.5M. 1.2m luminaries should at least use D=1.5M integrating sphere to measure.
If you test high power small size HID lamp, how do we choose Integrating Sphere? If the power of HID lamp is over 200W, we generally recommend use D=2.0m integrating sphere, we will not suggest small integrating sphere because of these reasons:
As the leading manufacturer of lamp test instrument, we can provide all kinds of integrating sphere, from D=0.3m to D=3.0m, and also constant temperature integrating sphere.
