Hello to everyone. I bought today these nice lamps. These are NOS, date codes vary from 2012 and 2013, also at the bottom of the boxes it says Philips, not Signify. Made in Poland Pila 2 plant.

The 400W ellipsoidal metal halide lamp. At rated current, the light is very similar to an incandescent halogen lamp, but when operating from a standard choke, this lamp cannot enter the normal mode.

High quality lamp. It has an outer glass envelope and 3 discharge tubes. The ballast heats up the electrodes, which is the reason why it lasts so long: 20 years. Made in Poland.

I bought these new bulbs for 500 dinars. The color code is 940, which means the lamps have a high CRI. Luminous flux 950 lm, base - 2G11, made in Poland. I'm quite satisfied.

I saved this tube from an old lamp that was in the power plant. While repairing it, the workers threw away the old lamps, and I saw this one and brought it home along with a GE 18W Chinese tube. This tube works, but one cathode is faulty. Lamp has a color temperature of 4000 K, the phosphor coating is smooth and the date of production is October 1968.

This is an unusual Polish metal halide lamp from the R&D Laboratory of POLAM. It was received via a Polish lamp collector without too much information. The suffix 'D' of the name LRJD would normally indicate Daylight colour, however the colour of this lamp is not white. It is about 8000K and slightly greenish. The mechanical construction is almost identical to Osram HQI-T lamps of the 1970s, it is clearly copied from that company's products.
