[time-nuts] Reducing lab noise with LED lighting.

[Raj]

As even LED have switchers in them, look for 12V LED spot lamps which run on AC/DC and give them a try. They have 3 LEDs and I don't think they have a switcher PS. A 12V transformer PS will work without filter cap IMHO. Low noise !

I am finding it is very noisy so I have started researching cost effective LED lighting and was amazed at what is available. On eBay there are 10 to 100 watt raw chips for $2-25.00  but that is equal to about 5 times the lumen of incandescent lighting. I was going to try building the heat sinks and supply into my existing bench fixtures.
