Lâmpadas entre 70 Watts e 80 Watts

[@That_2_guy2T]

I'd say HPS wins as they are brighter, lower power, and have a good color temperature. But MV lasts longer, I've seen some last over 40 years.

[@Naguals_HID_Lamps]

I agree. HPS lamps have more lumens per watt than MV lamps and their color temperature, which is mostly 2000K (I also have one that is only 1900K) is more pleasant to the eyes and also causes less light pollution and thus the night sky is brighter with them and more beautiful. However, they have a low color rendering index ("white sodium" is an exception), but overall it's perfectly fine for lighting roads and outdoor spaces. And yes, there are MV lamps that are 40 or even more years old and still working. I love all HID lamps.🙂

Where did you get the light holders?

[@Naguals_HID_Lamps]

These light holders are classic table lamps with an E27 socket without lampshades.🙂But I only use them for these videos, because they have plastic sockets and not ceramic. I didn't change them, because i don't normally use these table lamps for HID. I use a reflector for HID, to which i also connected cables, that have L, N and also PE wires with 1.5 mm². These table lamps only have cables with two wires (L, N) with only 0.75 mm².
