Hi Gents, What are your thoughts and exp regarding these ss nozzels from Pelam. Does the increased efficiency- if any- represent any danger reg to the heating of the lamp glass? Does it make the lamp more or less valuable with reg to authenticy? Haavar
Hi Haavar, as it is a bolt-on item it will not change any value (you can take it off and replace with whatever you want). Not having tried one myself, I'd like to hear the opinion from someone who has. I am as curious as you! Best regards, Wim
I have a stainless steel nozzle on one of my lamps, and the only benefit that I can tell is that it doesn't tend to loosen over time like the ceramic ones. The loosening tends to promote pulsing (IMHO) that can be annoying. Not really sure if they are worth the money since you can put stove seal on a ceramic nozzle to keep it in place.
I've never tried a stainless steel nozzle but I'd guess another advantage would be that they won't break when they're dropped...
There is no benefit at all besides the wallet of the seller. Loosening: New replacement ceramic nozzles seem to be made not to the same standard as the designer had in mind. I have had new 350cp ones which compared with the old ones did miss a whole winding of the thread. (is this good English ?)
One can still find German made Ceramic in the USA, they are a premium price compared to China made nozzles.. Prefer to keep my lantern all German if I can. Nozzle Glows cherry red when cranked up.. never has loosened on me yet. I keep a spare tho. BriteLyt offers the same Chinese made Stainless product here for an even higher price.. I Question their claims "With EZ-Cook attachment, this stainless nozzle increases cooking performance, especially in higher altitudes. (Tested in High Sierra’s) 50% to 100% brighter light above 400 watts." http://shop.britelyt.com/500cp-individual-parts/nozzle-stainless-steel-part-3-ss/ Living and camping in the High Sierra's of Nevada, 1400-1900 meters above MSL the only way to obtain higher output would be to increase the fuel supply and the Jet/Nipple has a fixed opening.. Their statement "above 400 watts" proves they have little knowledge that watts is a measurement of electrical current, not light output.. Marketing Hype imho..
A Watt is a measure of the rate of conversion of energy, equivalent to one Joule per second. As such, it would include the conversion of chemical energy in a fuel to heat and/or light in a lamp or stove. But I'm always dubious about any claims BryteLyt have ever made, are making now or may ever make in the future...
Hi, I never used a stainless steel burner myself because there are a lot of people in the german pelam forum that have experienced serious problems with those burners. To mention some: The brass mixing chamber right above the burner gets damaged due to the different expansion ratios of steel and brass, in some cases the burner has dropped off because of the widened threadings, the burner disc gets burnt and the middle section falls off, corroded parts of the burner disc damage the mantle, the pre heating with meths is difficult when it's cold outside due to the bigger amount of metal, when in use the mixing tube tends to glow red due to the better heat transfer of the steel compared to the clay burner. Maybe I forgot something but all the above prevented me from trying one by myself Stephan
400 Watts of light output. is for sure nonsense. That expression which simply was taken by quite some companies without any idea or knowledge of they were (are) talking about. It first was brouht up by Heinze - but in a correct way. It was a description in their catalogues: "A 500 HK Petromax lantern provides light comparable to a 400 Watt electric bulb." This is where the "400Watts" everyone is talking about comes from. Some other people even provided a formula to convert HK (or CP) in Watts 1,25 HK = 1 Watt. Absolute nonsense, junk, rubbish. But it tells a lot of the technical knowledge of these people: none. Erik
Except they should have said 'equivalent' rather than 'comparable'. But let's just leave it there, eh - I already feel my other German friend breathing down my neck...
Considering the design has been around for almost 90 years, if a metal nozzle would have worked better than a ceramic one I'm sure we would have seen it ages ago. The ceramic does a good job of isolating the heat from the relatively thin brass of the mixing tube.
A member of the german forum made a combined mixing chamber/burner nozzle out of brass. I haven't found out what the result was but there was one point against that design that you weren't able any more to fit the mantle support for the two-hole-mantles. Another disadvantage of a brass burner is, as already mentioned, the overheating of the mixing tube. Stephan
Hi I once bought one of these steel nozzles, but I haven´t noticed any significant improvements. If there is an advantage, the steel nozzle is more solid and will not break when unscrewing it if it´s stuck as the ceramic nozzle may do. I prefer the ceramic ones 8) . Regards Niels Chr.
