I have only done a test in my darkened basement, but this seemed to work very well: https://victory-products.com/collections/lighting-victory/products/aa00287r It's far brighter than something like a LED indicator light but nowhere near the brightness of your typical BA9S LED (and I couldn't find o

Dennis, I should add that it matters if the LED bulb distributes the light differently. If the lumens are the same, but the light distribution is different, then I would think the bulbs would not be equivalent. Gary ~~~_/)~~ On Mon, Sep 4, 2017 at 2:35 PM, Gary Russell wrote: >

Dennis, there is no accurate way to convert power (V*I) to lumens. Basically the temperature of the filament will drive the lumens value. Leslie. On Mon, 9/4/17, Dennis C. via CnC-List wrote: Subject: Stus-List LED bulb lumen equivalents To

Dennis, Watts is watts. A 3.4 watt bulb at 12 volts (0.28 amps) will draw 10x the current as at 120 volts (.028 amps). but the lumens should be about the same, I think. Gary S/V Kaylarah '90 C&C 37+ East Greenwich, RI, USA ~~~_/)~~ On Mon, Sep 4, 2017 at 12:19 PM, Dennis C. via C

This link to a GE miniature lamp catalog contains a wealth of information. Brightness is expressed in "spherical candlepower", where one candela is approximately equal to 12.5 lumens. Don't get distracted by sites with purist definitions, this is close enough for farm use in this context. http

I replaced the bulb in Touche's binnacle compass this weekend. Really wanted to look at an LED bulb but got hung up on the brightness. I just replaced it in kind from an auto parts store. The original bulb was a trade number 1891, 3.4W, 12 VDC mini-bayonet (BA9S) base. It's not difficult to fin
