I make one more update as my HK150 has now been working perfectly.

What I found out was that I had a loose thread between the parts 34 and 33. I have had the VA burner installed and with it I got this new mixing chamber (34) which was probably not for this lantern. I changed back to the old mixing chamber and there has been no more smoking and flaming. This is strange and I wish I had realized this earlier I also changed the complete carburettor because the needle always went broken probably due to a not-straight rod inside. Now it works fine and I have the old carburettor as spare parts for something else.

At the moment I am watching both my lanterns giving light to the Halloween evening

Now that I have been able to compare this almost new HK150 to my old Hipolito 350, I realize that this HK150 is still not working too perfectly.

It works, but the problems are, especially after the start up that there are flames around the mantle, and a lot of smoke. This lasts for some minutes, then it becomes better. 3, 4 or 5 cups of alcohol should be enough for preheating and the mantle lights up but not properly.

This flaming already has made white marks on the glass. I have a spare glass but I don't replace it before the lantern works better. I also have the whole carburettor to change if needed.

Does your HK150 start properly or are there flames & smoke ?

OK thanks. I ordered spare mantles that were specified only for the HK350.
About the reflectors, I think top reflector is a good choice for a garden light (I have it on my HK150) but if someone has experience from the side reflector or the beamless glass, any comments are welcome.

Today I finally tested the lantern. I feel a kind of lucky, it works perfectly. I only had to oil the piston to get pressure in the tank and put a new mantle.

Some questions I still have

Is the working pressure of this bigger lantern the same 2,5 bar as in the smaller one?

There is still some small spot in the tank body where the chrome is missing. Is there any sort of paint which might be considered for a small touch-up repair or should I leave it?

Has anyone tried the side reflector? Or is the top reflector correct one if you use the lantern as a garden light?

I think it needs some reflector it is so bright

Is the mantle the same for HK350 and HK500? Pelam has different product numbers for these. But someone in ebay offers same mantle for both.

Descaling agent cleaner worked really great. It started to shine already just after cleaning I hadn't even started the polishing yet. The only thing that is still not in back in chrome color is the top part of the lantern. I guess that it has just been working so hot that the surface is too damaged. I hope there will be still one more picture soon when the lantern is lighted up.

Thanks for your hints.
I understand that if I change the nozzle and needle it actually is the same as HK500.
Does someone know about the consumption between the two options ?
Has anyone used metal polishing pastes like Autosol?

Nice to hear, I can be sure I get spare parts.

So this equals to HK350. What are the main differences between models HK350 and HK500? They have the same dimensions and look the same.

Also please comment if you have any advise for cleaning & polishing. I think this lantern has been stored outside for years and there is some job to do with it.

I found a pressure lantern Hipolito H302/350, a used one. I am new to these lanterns so I would have some questions.

What is the manufacturer "Hipolito" and where is this lantern made?
Is it possible to know what is the age of the lantern (approximately) ?
Are Petromax parts suitable for this lantern? It looks quite much the same. Probably I will need parts like needle, jet, gaskets, etc.
What kind of a lantern is this, is it good or bad? I just bought it as the price was very affordable. I wanted a one
which I can try to restore.

I am thinkin should I just try the lantern to see if it works or put it already in pieces and start polishing. It looks quite terrible for the beginning. It is not rust but some sort of oxidation. Is it possible to make it shine again?

One question: I can see that there are two hole mantles available also for the HK150. But I can't find anywhere the holder for the two hole mantle, it is not shown even at Pelam's accessory lists. Is it available, and if not, is there a reason? For the HK500 I can see it everywhere. Is it a good idea to have it on the HK150? I was thinking that it might last better when moving around.

When I pump my HK500 to the red mark in manometer it will burn at least for 6 hours without pumping.

OK this is an important point for me. I like the small size of the HK150 but what I don't like is that you have to pump more pressure latest at every two hours because the light is already dim.

Zitat von magnuken

The light from HK500 is very bright and and it is not pleasant to watch it straight. Therefore I use in my HK500 a side reflector (s5) and also now and then a top reflector (top5c).

Started thinking if the HK500 could be used in real for the "torch fishing" (don't know the correct word). We will do it sooner or later as we are very keen on fishing with my sons, maybe this lantern could work? More light the better in that

May I ask in the same topic:

what are the main differences between the HK150 and HK500?

I know the HK500 is more size, more power etc. but e.g. do you have to pump more pressure less often than on the HK150 because the tank is so much bigger ? If the light equals to 400W lamp, is it still usable in "normal conditions" or is it too bright to watch?

I want another lamp, and I am considering between another new HK150 or HK500. The price is almost the same.

Day no. 3 and it is still working. A few hours every evening.

I don't remember how it was in the beginning, but now when I pre heat (with 2x cup alcohol) the mantle is always in flames when I start to pump pressure and there are black areas. I have to wait a couple of minutes then the flames disappear, the mantle becomes clear and light becomes bright. Then it is fine as long as it burns.
Is some light smoke normal? This lamp is very hot.

Thanks for all these advise.

I no more know what is effecting what but I adjusted the jet and mixing tube gap to slightly less again, I changed back the old jet just without having better ideas at the moment, retightened everything and fired up with the "soft start" which I actually now like more... the mantle was again getting in flames. Felt a bit in despair just watching the flames but then slowly it started to burn better. The flames disappeared, the black areas from the mantle disappeared after a few minutes and the light became bright.

At the moment it is lighting so fine at my backyard

The lantern is quite new (I bought it as new) and my fault was that when I had the first problem I started to reassemble the parts (pre-heater, carburettor) for cleaning etc. without knowing that this thing is somewhat sensitive to any "screwing" - at least if you don't know exactly hot to put it back.

If it now continues working, I won't touch anything on it except changing the mantle when needed.

One more change before this latest "success", I now use PELAM lamp oil. The previous one I used should also be good quality (no smell, no smoke) but maybe this quality is even better.

Today I tried the "soft start" but the result is the same, the mantle catches flames.
I refilled the cup 4-5 times. For sure it finally was hot enough, this is not the case
How sensitive is the HK150 lantern for the air gap between the jet and mixing tube?
I increased this a bit adjusting the nuts on both sides, to achieve a brighter flame as advised.
Maybe this was not good?

Could someone give me some hints as today the HK150 is catching flames in the upper part of the lantern and does not light up? Flames around the mantle and the upper part I did the pre-heat with the pre-heat torch long enough. I have everything tightened. Does anyone else have this HK 150 ? If there is someone, could you tell me is it ever possible to have it working properly? I have read that the HK 500 would need much less repairs, is it correct?

My Petromax HK 150 is lighting again.

I did the underwater test and found the only leakage was on the preheater. It may be that somehow the lamp oil was spraying from the preheater because I found no other faults. I made the preheater sitting more properly with no leak, it was slightly bent. It really looked earlier that the leakage is between the carburettor parts, so the underwater test was a great advise.

Then I still had some problems to light the lantern. I have learnt that this is maybe not the most reliable thing I have owned but today it works after some re-assembly and cleaning. It may be I still have to clean the carburettor needle and jet again because the light is flickering a bit and is not as bright as it could be. I could also replace these as I have now spare parts. What is normally the reason for a flickering / not fully bright light?

Hi. Could someone advise what could be wrong as my HK 150 is leaking lamp oil from the carburettor? I think it comes between the parts 152 and 153. I have had the carburettor upper and lower parts disconnected and now I have tried to put them back together a few times. If I just pressurize the lantern there is no leak but when I turn down the wheel the lamp oil is coming from the spray nozzle but also leaking from somewhere around the nut between the carburettor parts. Makes no sense to use the lantern before it is fixed
