This is HOT!

10,000 Watts of hotness! :wub:

It's ballasted so running at 67% power. The transformer really grunts (love the 50Hz hum too!) on startup as cold the resistance of cold wolfram is quite low. As opposed to "across the line" operation, this kind of startup is soft.

LOL at the guy staring at it. Didn't anyone tell him not to look at the sun?

 

[highland145]

No one told the guy to not look into the sun?

Edit: sox beat me.

True. Someone should follow him around to capture him winning the Darwin award.

What's up with ruby and watss

 

[Anubis]

WTF is that used for?

 

[highland145]

What's up with ruby and watss

Cause Ruby thinks watts are hot.

LOL!

Oops. Typo

Old projectors used them.

I²R is watt its all about!

And you do the hokey pokey and turn yourself about.

In all fairness, watts are kind of hot.

Wow I need this in my garage. It will make it brighter and heat it at the same time!

Wonder if they use something similar in cell towers. We sometimes have to send guys up there to change the bulbs since we get alarms that the bulbs burn out, but I've never actually seen the bulbs myself.

Yes the more you have the hotter it gets.

IIRC most lights on towers where required are Xenon flashtubes. They flash at high power during the day and at night switch to a psuedo-CW mode where they turn on briefly (not a flash) and are much dimmer. Radio towers use incandescent bulbs - as high as 600W. They are undervolted and have a direct current soft (inrush eliminator) circuit to enhance MTBF. LEDs are taking over and can function like the aforementioned Xenon strobes and have a traditional "glow on - glow off" of incandescent beacons without the maintenance.

All the cool kids use |V||I|cos(&#920

 

[Matthiasa]

And the even cooler kids actually remember you need to use rms values when using that equation.

Fuck,I'm old.

 

[KevinCU]

The cooler kids assume the cool kids know to use rms values in that equation.

 

[Matthiasa]

The cooler kids would have used the correct symbols, or at least would have denoted with subscripts.

 

[wirednuts]

if you factor the amount of resistive energy in one spot with the condition of the area it is located, the most surprising part of the video is seeing the garage in tact at the end.

Meh, in my class we're taught to let V and I be rms values and let Vm and Im be peak values mainly because rms gets annoying to constantly write.

So this would be a bitch?



'sup, Kevin?
