WebNov 3, 2024 · Mr. Carlson’s Lab video channel also designed a similar dim bulb tester a couple of years ago. It does not include the AC limit on lamp but includes the variac and isolation transformer into the design. Mr. Carlson’s videos are great and always include lots of safety information! WebThe tester will have a 3-way light bulb – 50/100/150 watt - that will be selectable by way of a 3-way rotary lamp switch. The tester will have both an AC ammeter and AC voltmeter, plus binding posts to enable the connection of an external digital meter if need be. The ‘dim bulb’ tester will have both a ‘normal’ and a ‘bypass’ mode.
