Playa lighting
Trying to power an 18' yurt with a 300 watt power supply during 12 hours of night (the equinox is on the 22nd) can take some thought. Consider the issue of lighting for example. Stringing a strand of Christmas lights might seem like a reasonable way to light the dome. The C7 bulb however can consume 6 watts each. Even the incandescent mini-light consumes 0.48 watts. String 100 of those C7 lights together and you'll sucking up 600 watts in only one hour. You'll consume 48 watts with the mini-lights.
To get a perspective on what these numbers mean, consider the following. The C7 lights would consume the battery's power in half an hour while the mini-lights would consume the battery's power in 6 hours.
A couple companies are offering an alternative to incandescent Christmas lights: LED lights. These lights resemble the mini-lights but consume only 0.08 watts. A 100 bulb strand will consume 8 watts. That's one sixth the amount of power. To say it another way, the lights will take 6 times as long to consume the battery's power or 36 hours.
There is a power loss during the conversion from DC to AC. The process requires a device called an inverter. While the efficiency of inverters differ, the ones I've seen incur about a 10% power loss. For simplicity I haven't included that figure in the calculations but for reference, the times would be adjusted as follows. The C6 would last 0.5 hours, not 6. The mini-lights would last 5.5 hours, not 6. The LED lights would last 32 hours, not 36.
A company called Inirgee sells LED lights powered from DC. Using those lights would conserve the 10% power loss from the inverter.
