Click to view full size image

This HPI Plus (no -T) Base Up lamp is coated. The spectrum indicates the DX coating just like the DX coated MV lamps. Also the sodium is not as driven as in the 250W HPI-T lamp (top strip). The lamp is glorious red at startup, for just about 2-3 seconds.

The HPI-T should be red at startup as well, as it also have neon-argon.

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

I've seen the HPI-BUS 400W during turning on. They are also red from the neon like you said. The light from the /DX phosphors, can be observed only with a spectroscope or a disc during turning on, because of the intense light from the electrodes.

Yup HPI-T is also red, but only for 1 second. HPI coated lamp above is a more vivid red for longer, then turns pink. I saw Lantern Vision's video of Philips HPI-BUS vs Osram HQI-E N/SI.. The HPI-BUS appeared very red also for just 1 second then turned pink (phosphor coating).

dor123: do you know the fill for the Osram HQI-E 250W/N/SI?? Why is it also coated?

The Osram HQI-E 250W/N/SI have also a /DX phosphor and it pinkish color is more visible during run-up, compared to the Philips HPI-BUS 400W
The filling of the HQI-E 250W/N/SI, is argon, mercury and Na-Sc, and it is a probe-start MH lamps for M58 ANSI ballast or a mercury reactor + 750V ignitor.

Osram HQI-E is an expensive lamp, only available from Europe or HongKong (ebay). Thanks for the info - I have many Hg + Na-Sc lamps so I will pass.

Is this EBAY LAMP similar or the same as Lantern Vision's coated HPI-BUS lamp?

The picture, is of the Master HPI-T Plus 400W, but the lamp for sale is exactly the HPI-BUS 400W. The HPI-BUS is also a probe-start MH lamp, but for european mercury chokes with no ignitor. May be suitable for 400W HX MV ballasts but not for CWA ballasts.
