List Members, Some important information follows - do not delete without reading first. It is well known that halogen lamps get sufficiently hot that they sometimes ignite adjacent combustible material causing a fire - although this does not appear, at the moment to be the case in this situation, which is usually the first thing people think of when a fire is mention in the context of these lamps, it seems this did not happen in the case recounted below as the bulbs were evaluated, would not work, and were thought to be burned out. A fire developed in my shop several months ago doing widespread, extensive damage, ruining the value in many expensive pianos. Although the cause of origin is still being investigated I am convinced that the fire began in a halogen work light in which, as I said above, the bulbs were not working, even though the power cord was still plugged in. The light had been plugged in to evaluate the bulbs which were thought to be burned out. They did not work; later, I belive, the light itself developed a fire which then spread into the shop. This light is the yellow and black worklight built by Chicago Electric and sold at Harbor Freight. It comes on an extendable tripod with two lamps mounted on a crosspiece. Each lamp is provided with its own switch. The power cord for this light comes up to a small black junction box out of which two cords then proceed, each to the respective switch for its lamphead. Additional information has been discovered, unconnected with me or my shop, which indicates that the connections in the interior of this junction box may be unreliable, and, if so, it is my opinion, they can indeed be dangerous as it appears that this box was either the origin of the fire or connected in someway to it. I have not disassembled one of these boxes even though I have several of these lights as they are to be preserved intact for later investigation. However, several individuals, unknown to each other, operating entirely independently of each other, have described to me the connections made in the interior of this box, where a crimp is used to attach the cord to a connector, in highly negative terms, basically, considering it dangerous. Of course, this is a fact I wish I had been aware of before buying the damn things. This crimp may loosen and cause problems and needs periodic attention. I presonally believe this contributed to the development of the fire mentioned above. For this reason it seems highly advisable to inspect this connection if you have such a light. One should be aware, if a loose connection does exist here, that it may lead one to think the switches or bulbs are bad which may or may not be the case. UNDER NO CIRCUMSTANCES SHOULD THE LIGHT EVER BE LEFT PLUGGED IN - BURNING OR NOT - WITHOUT OBSERVATION. I believe it can also lead to a fire. Let is remember our OT list discipline; if one wishes to communicate with me on this subject, unless it has a general interest to the members of the list, please contact me privately.
