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

[Bob Camp]

Hi

The thing that makes the CFL's nasty for lab use are the cheap little switchers built into them. Conventional LED lights also have cheap little switchers in them. Doing them with a 30% efficient linear regulator gets you back to halogen type lumens per watt...

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.
