Florescent Light Upgrade In The Lab

Hi All,
Decided to place a light above my lab work bench, after doing some research on what type of light LED, Florescent or halogen I came across Ben Krasnow site explaining the difference between T12, T5 and T8 bulbs and efficiency vs light output, see video below.



I already had a bad cheap T12 "shop light" with a bad ballast that burnt out a few months ago, I know I'm a pack rat. Bought a ballast and two t8 bulbs at Home Depot GE232 -120RES-DIY Stock number 71037 for $14.99 and two GE F32T8 SP41ECO 4100K around 5 bucks.

The wiring was a bit different than the old ballast, just follow the drawing on the new ballast, bi pin are the same.

OLD


NEW


Finished


Best of all there no annoying hum and it's very, very bright located about 24 inches from the bench surface. Double the light output at half the current of my old T12's! Great projects for a newbie!

Budget Crisis from an Engineers point of view

Hello all, I was discussing the current budget crisis with a friend of mine. A good point was brought up.....if anyone of us had a similar budget to run our homes we would be in serious trouble. Let me give you the numbers

Us Income__________2,170,000,000,000
Federal Budget_______3,820,000,000,000
New Debt___________1,650,000,000,000
National Debt_______14,271,000,000,000
Recent Budget Cut_______38,500,000,000

Okay kind of tough to wrap your mind with large numbers, let's use powers of ten and cut some zero (eight places) to make it more manageable.

N1IR Income__________21,700
N1IR Spent___________38,200
Credit Card New Debt____16,500
Balance on Credit Card___142,710
Cut Made by N1IR_________385

With simple powers of ten you can clearly see the problem, why can the people in washington see this? Food for thought....N1IR
