Recently I found myself needing to buy some LED bulbs. All of the bulbs, around my light bulb, were bought at Menards. You should be able to find these at really any home improvement store. These are the only ones that I kept. When I was testing to find the ‘good’ LED know that I ended up returning about 2 times the amount of bulbs that I kept. If you are going to get any of these bulbs double check to make sure they are good. Also make sure they are EXACTLY the same bulb as the one in the picture.
Like I have said before you will need to test LED bulbs to see if they produce dirty electricity. The easiest way to do this is with a Microsurge meter, which can be bought here and instructions can be found here.
