			==Basic Instructions==
			To build the halogen heater, take 2 118 mm halogen holders, and solder them in series. SOlder them to the 200C wire that would otherwise attach to the nichrome heater element. Since the wiring is no longer hot, solder will not melt at the connection - making the halogen heater actually much more robust and easier to build.

			After you are done soldering insert the heaters inside the heat bed, facing away from each other with the wires inside, so that the heaters are facing the 1/2" conduit sides of the heater bed. This way, the wires are not being heated.

			The halogen holders should be parallel to the 5-1/4" lenght of the conduit.

			Use the carbon fiber blanket on the bottom for insulation.

			Screw the print surface on top of hte conduit. The glass of halogen lights should be pointing to the side, not up - that's the only they will fit without the glass of the halogen bulb touching the top plate.

			Note that one of the ends of conduit is taped, see picture below. The inside of the conduit is a convenient place to put the thermistor. One end is taped up, so there are no drafts inside the conduit, which would make the thermistor temperature reading inaccurate.

			*Note that for the 6" bed [[D3D Universal 2]], 118mm (about 4.69") is the longest that fits in the bed. Pay attention to not using longer than 118 mm for a 6" bed - but longer bulbs can be used for larger beds.
			*We have had a heater element under testing 24/7 for the last 2 months - there is no indication of forthcoming failure, and we expect the lifetime of the heater to be well over the 2000 hour typical [https://www.google.com/search?sxsrf=ALeKk026QG9BbsZl0rNsBS9KmerMgczY_w%3A1602863734253&source=hp&ei=dsKJX6q8DJDYsAXHkpG4Cw&q=lifetime+of+a+halogen+bulb&btnK=Google+Search&oq=how+to+configure+nvidia+geforce+gtx+1650+super+on+linux+mint&gs_lcp=CgZwc3ktYWIQAzIFCCEQoAEyBQghEKsCMgUIIRCrAjoOCAAQ6gIQtAIQmgEQ5QI6DgguELEDEMcBEKMCEJMCOggILhDHARCvAToLCC4QsQMQxwEQowI6CAgAELEDEIMBOggILhCxAxCDAToFCAAQsQM6AggAOgQIABAKOgYIABAWEB46CAghEBYQHRAeOgcIIRAKEKABUMsQWOmzAWD8tAFoBnAAeACAAeQGiAGhS5IBDTExLjQ3LjMuMi42LTGYAQCgAQGqAQdnd3Mtd2l6sAEG&sclient=psy-ab&ved=0ahUKEwiqz4DcvLnsAhUQLKwKHUdJBLcQ4dUDCAk&uact=5] lifetime of a halogen bulb if we are using 240V bulbs and running them at 1/4 power by using 120V.
			* JET - Tried new 1" bars on heated bed and these caused smoking once heated to around 50C. I believe this is caused by the coating on these particular pieces of metal.
