Diazed fuses were common in street lights here in Brazil, at the time when Philips HRP with mercury 250W were used in squares,ended up being extra protection for the lights fixtures and the main switch contactor. Good times.
Nice video! I wish lanterns with two bulbs inside are common where I live. There’s a main road not far from me that uses CPO-TW lanterns inside of Urbis Cabrios. Some of them are burned out with only one bulb working or two bulbs burned out altogether.
The luminous efficacy of mercury lamps decays with age, so it is common practice to replace them when their light output gets too low to be economical.
Good quality MV lamps indeed never "burn out" (but eventually need replacement because they became too dim). Unfortunately, it's not like this with lamps made in China, even for big brands such as Philips. Those *_do_* burn out, sometimes as early as after 1-2 years of service. The Philips HPL 4 Pro 125W lamps "made in PRC" are especially bad. I've seen them stop working completely all the time.
@@martinweizenacker7129 I had a Regent branded chinesium 100W lamp go totally dead in a few months. Based on my testing, the arc tube leaked into the outer envelope as there are now argon/nitrogen discharges in the outer envelope and no mercury discharge in the discharge tube when tested with one of those probe type neon sign/lamp testers.
@@randacnam7321 Yep, badly sealed arc tube. Also the arc tubes are smaller compared to good quality lamps, which puts more strain on them, thus shorter lamp life. Another common issue with Chinese MV lamps is the built-in resistor for the starting electrode or the starting electrode itself go bad. Result is, the lamp can no longer ignite and is dead.

Lol the 🚦in garden 😂🔥
19👍😊hello nice video thank you new lamp mercury 2x 80w Philips, congratulations collection, nice service
Blijft een mooi armatuur
4:00 are those fuses
Yes it is fuses!
💡
Dosent mv like never burn out though??

Hello, have you ever seen Philips HRP in HPS lamps (also call SRP) ??
I like old street light
why did you use an 125w ballest
It's an 80w/125w ballast so both work
@@thelamppostchannel you mean 2 lamps can work wit the same ballast
@@sheeesh13
yeah if both bulbs add up to the wattage of the ballast
What does HPL in full name? Its my first time seeing this
Wtf never seen this with 2 lamps 😱😲
2×80 W more erergy efficient that one 175 W they can be turned on in half power
👍
You Man es Hmmmm
