@@HIDSON-TPIA I don't think I've ever seen a HPS explode, only with a capacitor bank, I believe the same applies to metal halide lamp with ceramic tube, but I'm not sure.
Certainly CDO and CPO ceramic arc halide lamps are safer but they are still dangerous as Philips has a warning for these lamps and indeed some metal halide lamps are extremely dangerous and Philips has an important warning for both UV as well as for explosion. no similar warning for HPS lamps, mercury lamps are dangerous, but less dangerous in case of explosion, but extremely dangerous because they emit a lot of UV radiation in case of arc tube failure, but I have never heard or seen it explode but definitely safer than metal halide lamps and xenon and metal halide lamps are the dangerous lamps out there, especially the older metal halide lamps that did not have the letter O indicating that they have thicker glass, these lamps are not lamps but powerful dynamite literally!! The internal pressure of metal halide lamps is 70-90psi, that is 4-6bar compared to 1 or 2bar internal pressure of HPS and mercury lamps! I'm really scared of metal halide bulbs, while HPS bulbs are much safer with almost no risk, so even without using a box they'll be safe to use, but if it's for outdoor use you always need a box and indoors it's good to use a box because you never know but you can use them without but NEVER PUT THE HPS LIGHTS DIRECTLY ON POWER AND NOT ONLY THE HPS LIGHTS BUT ALL THE GAS LIGHTS!!!, while the metal halide lamp must always be in a fixture for us safety even if you use it for a while! but it's not that HPS bulbs can't explode, maybe 1 in 1000 a HPS bulb will explode but only in very rare cases and only at the end of their life and if that happens the inner tube and glass won't break much in It at the same time people made a video where they put 70w HPS bulbs in a 1000w ballast and only the arc tube was broken but there was no damage to the outer glass, the metal halide bulb will probably explode with a lot of force, if it happens with HPS bulbs it doesn't it will be done in the same way and much milder and extremely rare! HPS bulbs are very resistant to almost anything, the most reliable bulbs out there generally along with LEDs and SOX, but some LEDs!!
In the UK, there were 5 foot 80W T12 tubes that were specifically designed to run on 80W mercury vapor ballasts that were made during WW2. Additionally, there are some North American high output T12 tubes with the R17D base that have very similar electrical properties to 80W mercury vapor lamps as well, but they are normally designed for rapid start ballasts, but should run fine on 80W mercury vapor ballasts if they are at least 5 feet long or so. In order to do this, you would need to use starters.
The usefulness of this method is only to entertain a lamp enthusiast. Furthermore, starters for fluorescent lamps are fine as long as the mercury vapor lamps have low wattages (50/80w), as starters have more and more problems due to the large amount of current that the ballast passes through. I know that all this can also be done with a simple HPS lamp igniter, but I've just never tried it yet.
Philips S12 or S16 starters work fine even with 125W MV ballasts. They don"t get stuck that easily
This is basically what retrofit HPS lamps do. The problem is that if the starter gets stuck the ballast will burn I believe
yes, infact this method is only for fun, i doesen't have real applications for mercury vapour lamp.
I've heard that metal halide bulbs are more dangerous because they can explode, but would it be safe to use them without light fixture?
Yes, they explode either at the end of life or due to inadequate ballast, mercury also explodes due to inadequate or shorted ballast.
therefore they are dangerous compared to HPS lamps which are much safer!

Nuovo video dopo un po di tempo!
eh si
Now I'm curious to see a fluorescent bulb run on a mercury ballast. I don't think that would work lol

very clever, but makes no sense for an Eol mercury lamp
