Hi! Today I tried to run Osram HQL 80 in series with Osram NAV-E 70W. Once they warmed up, the current fell to 0,7A and light shut down. If we can, we could talk more about discharge lamps through some social network?
Hello. How exactly did you start them, or what ballasts did you use, and also what was the length of the cable from the ballast to one and the other lamp and what was the cross-section of the wires? And feel free to write to me on Instagram, whose link I have here on the channels.
@@Naguals_HID_Lamps I ran the lightbulbs exactly, as typical High pressure sodium or metal halide control gear, except the lightbulbs were in series. Cabls were used 1mm² cross section. Ballast choke was used 70W HPS/MH, eventulay I added in paralell 18W fluorescent tube ballast choke, didn't helped.
@@arnislacis9064 Yes, the Mercury Vapor lamp can be started in other ways (for example, there are also Self-ballasted Mercury Vapor lamps). And a magnetic ballast for MV lamps is therefore not necessary. However, there are many details that can shorten the nominal lifespan of the lamp, the efficiency, or the electric arc simply cannot be held in the arc tube. I don't know if you use electronic or magnetic HPS/MH ballast. But the use of a starter (which cannot be avoided in an electronic ballast for HPS/MH lamps) can destroy the resistor that is inside the Mercury Vapor lamp. It should also be taken into account that the ignition voltage for the 80W HQL lamp is 0.198 kVp and the nominal voltage is 115 V. And for the 70W NAV-E lamp the ignition voltage is 1.8/5.0 kVp and the nominal voltage is only 90 V. I personally use it for 80W MV lamps only magnetic ballast, namely Philips BHL 80 L202 and it works great.
