Whilst this is a nice set of power resistors, half of them are through hole resistors with coloured bands on them to indicate their resistance. Unfortunately there is nothing to indicate the actual power rating and with them being of various thicknesses I assume they aren't all the same power rating either. I contacted the supplier to ask if they had any more information but they responded that they didn't. So it's just a guess really as to what the power rating of some of these resistors is, which is a pity since the high power rating is their main selling point.
