[sudo-discuss] lighting options

[Jake]

I got a 66% refund from Aliexpress after sending pictures of voltmeter, 
ammeter, and LEDs proving that they're 5.5 watts instead of "16-20" watts

so i spent the money on "10 watt" white LEDs from electronic goldmine, 
three for $12, i got 12 of them which should be enough to replace an 
entire overhead fixture in sudoroom with them - and have lots more light 
with slightly less power.

i don't know whether they're hot or cold white.
