Coleman lantern CP

3278. Coleman lantern CP by Jon Mulder (thejmfc@hotmail.com)

      Just a wondering about Coleman lanterns. What candlepower do the common models of lanterns produce (220, 200a, etc.)? Also, are the Kerosene models brighter (don't know my Kero model numbers off hand...)? I've searched briefly for this information, but it seems hard to come by. Please pardon the lack of a picture, and thanks in advance for your information.

  Jon: Not a simple question but I have compiled a list of all the lanterns sorted by CP. I may have one or two wrong but by and large this will be correct. Coleman stopped publishing the power rating on their product because they felt that in general the buying public did not understand what it meant. With Coleman product the lamps when new would perform to the rated power. However as they get older and burner parts get worn they frequently will not, even after cleaning and new generators being fitted. So for what it is worth here is the table.
  
  150 cp
  222 Peak One (125CP); 222A; 222B; 226; 229; 3022 (125CP); 3025 (125cp)
  
  200 CP
  214; 214A; 222 Colmax; 234 (175 CP); 241; 241A (200 – 250); 241B (200-250); 242; 252; 252A; 282; 285(220 CP); 286; 286A; 288 (220CP)
  
  250CP
  241G; 243 (All variations):
  
  300 CP
  All the Quick Lite models; 200; 201; 218; 220 (All variations); 223; 225; 228 (All variations); 242 (All variations except A); 246; 247; 249 (All variations); 275; 275A; 290; 290A; 295; 321 (All variations); 325; 325A; 333 (Colmax); 335(350CP); 339 (350CP)
  
  500 CP
  206 (550CP); 236; 237; 238B; 555 Colmax; 621 (All variations); 625 (All variations); 635; 635A (550CP); 635B; 639 (All variations); 2000 Northstar (550 CP)
  
  I hope this gives what you want. ::Neil::

    Yes, thank you. That is what I was looking for. I understand that as a lantern ages, performance may suffer, but at least this gives me some idea of how different models perform with all else being equal (not that it ever is). I was somewhat suprised to learn that the 200 and 220 series are rated at the same 300CP. You'd think that with twice the mantle working for you, you'd have at least a little more light.
    
    Again, thank you very much, as it looks like that list took some effort to compile.

      Jon: Power output from a lamp is governed by the quantity of fuel burnt in a given period. It has nothing to do with mantle size or the number of mantles. For shadow reduction two is indeed better but total power out depends on the gas tip size which determines how much fuel passes. Power out also varies with pressure. This is simply because at a greater pressure more fuel is burnt. You can actually successfully run all the 300 cp twin mantle lamps on Coleman #20 mantles. These are nominally 150 cp mantles and two of them will handle 300 cp as well as the more common #21s which are 250-300 cp mantles. I did say I may have one or two of those wrong so don't assume it is cast in stone. I also missed a few models out. 202 is of course the same as 200 and model 231 is a twin 300 cp kero lantern. Without a detailed check there may be others I missed but by and large it is reasonably correct and complete.
      
      Kerosene lamps do not burn brighter than gasoline ones but are perhaps more efficient in that they burn less fuel. In simple terms kerosene has more latent energy per unit than gasoline. ::Neil::
