For LED lights the difference in light output may not be as dramatic as it is with incandescent bulbs but it will not work as well.
Can i use a 120 volt bulb in a 12 volt system. This is a high-quality LED bulb 93 CRI and an R9 of 60 and the model is unavailable for European voltages. It makes no sense to try to use a 12 volt bulb in a socket that is fed by 120 volts even if the socket is the right size because 120 volts is ten times bigger than 12 volts. If we are discussing screw-in base bulbs Europeans mainly use E14 and E27 bases.
Clearly in todays environment you should not use 130V bulbs in 120V or double life bulbs as they are marketed you should use LEDs which will save the labor of many changes if you are a business around 45 changes at 30 per change and a lot of electricity about 20- per incandescent lifetime or 100 per LED lifetime as well making the 10 or so cost for the bulb a. 12 volt bulbs are smaller and can be less obtrusive in any landscape setting. But you need to use wires with a hundred times the cross-sectional area ten times the diameter which apart from being wasteful is very very costly.
No a light bulb rated to work in a 120 volt lamp will not work properly in a 12 or 24 volt low volt lighting fixture. The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation. I wanted a 12 volt lightbulb For my home RE system that looked and functioned like a normal light brightness etc.
I found these at LOWES for under 10 and decided it was time to hack. The bulbs are also available in different low watt styles and can be. This handy tool has multiple uses.
But one that didnt use a lot of power. If you did get a. The 12 volt system offers the homeowner more flexibility for future changes than the 120 volt counterpart.
I dont believe it will harm the fixture. On the packaging it says Use only on 120 volt AC circuits and on the light-bulb itself it says 120V 60Hz and 112mA The trouble is of course that the light bulb was designed for 120V mains voltage while in most European countries the voltage is 220V-240V. Therefore a quality multi element pendant ceiling fitting with say 5 lamp holders fitted with 1224V OnSolar DC led bulbs will produce as much light as a 125W of combined incandescent power.
