12v Mattress heating pad woes
Last night was kinda chilly. An hour before climbing into bed I, plug my 'watts up' meter inline with my mattress heating pad, crank it up to 7, check out the amp draw, and see it is only half of n...

Some of the Chinese engineering I see makes my hair stand on end and that ain't no small feat. Like that 84 watt power supply with 26 gauge power input wire. Those 50 smd LED plates have wire smaller than that (30 gauge?).With the flaky power down here, I'm using the Samlex couple to the WFCO and Lifeline to generate UPS to my most precious items including NinerBikes Galaxy II which he loaned to me permanently.
Wanna blow out a set of 9002-9008 headlight bulbs? Increase factory wire size from relay to connector socket from 18 gauge SAE to 12 gauge AWG.
Honorable Chinese Engineering. Touch it, and it'll flame the first windy day.
Just got my hands on a pair of 30 watt LED floodlight fixtures. 120 vac. Plugged them in. One was gulping 42 watts, the second 39. IR'd the chips after 10 minutes. 184F, and 177F. The heatsinks were too warm as well. My review will appear on Amazon soon. Hope the vendor has a pint of Merthiolate and a square yard of bandages. Now I have to start looking for super low dropout converters or start a series connection of silicon diodes. These fools are screaming for US government regulation and we all know what that's going to mean.
