What are the trade-offs for using 12-Volt lighting versus 120-volt lighting? - what type of light does halogen give off
I equip my long dreamed of the comic shop with light (opening in January) and equipment for lighting 14 watts, which reflects the compact fluorescent lamps (R20, purchased with the standard basis).
Other options, which I as yet marketing MR16 halogen lamps to give a good light, but heat and more power.
To add these lights, I must add an additional 15 A circuit breaker in my box.
The question I have is whether the use of a lighting store from 12 volts are available (with the type of MR16 lamps) all the energy (by the electricity company billed kWh), or just want to say, we need more amps.
Watts = Volts * amps
For example, a 30-watt light bulb 30 watts at 120 volts, so it uses a circuit of 25 amps.
30W = 120 (.25 amps)
Within a radius of 12 V =
30W = 12V (2.5 Amps)
Is that true?

There are far too easy here with the Volt and Ampere examined.
ReplyDeleteYes, this is your calculation correct. The low-voltage limit is the size of the driver - it requires more son 12V side. However, the processor run-120V, which is near the lamp (s) is so is not the problem it seems.
A low voltage system uses more energy per watt, because the processor "loss". However, there are some incredible elegance and fastening systems to low voltage. So the "look" you want the numbers here.
Fluorescent alone can not save a good choice for a comic book too. Despite the efforts of manufacturers, fluorescence spectrum is not yet in full color very well. Very saturated especially the reds. Jewel has been with quartz lamps for the year because of the quality of light.
Disadvantage: expensive lights and heated (UPS air conditioning load).
Another possibility is incandescent PAR lamps. Appropriate quality of light, less expensive, butwhere the heat is back.
In general, if the lighting qualities of color, light you want with Kelvin estimated as high as you can afford to purchase / installation, operation and maintenance. 6500K is a common option (http://en.wikipedia.org/wiki/Color_tempe ...
Low have limits on how many lights per transformer. It can create additional costs for the installation of additional circuits of the switchboard, connected to the local codes on the base.
You can keep this light costs:
Clinging to things that are usually available in your area are available.
Use fluorescent lamps for general area lighting and windows closed
Add high-quality lamps for accent lighting and functionality
With 12 volts instead of 120 volts, the load current in the circuit is 10 times greater than in the use of 120 volts. Therefore, the circuit of the interface are larger. The downside is the installation would be more expensive. On the other hand, a distance of 12 volts is not a risk of electrical shock, although some terminals are not isolated.
ReplyDeleteYou are correct in essence. I would like with the 120 volts, anyway ... In this way, you do not have to worry about the processor.
ReplyDeleteYou use the same amount of energy. But it takes much longer speak wiring.Not transformer. GB 120 V.
