The PHILIPS MHN-TD 70W/842 discharge lamp (double-ended tubular) is a quartz metal-halide high-intensity discharge lamp. It emits cool white light at 4,200 K (CRI 75) and about 5,800 lumens, with excellent stability over time.

It runs on suitable discharge control gear (ballast + ignitor) matched exactly to its wattage (70 W) and type: it never connects directly to the mains. Its outer envelope screens UV (UVC). Warm-up takes a few minutes; after switch-off, let it cool before restrike.
