Can I change this ceiling light to LED? This is my basement light, which is not enough bright for kid. Since I have moved this house, I only replaced the brighter light bulb, but now decide to get wider and/or brighter LED light. If so, I need advise how to and need to ask before buying anything. I attach the pictures that what I have and Amazon link that I want to replace.

Mine is 8" round and it is a 12" round with 1580lm. Currently, I use 2 light bulbs which is 60Watt each, which is the max watt I can have on that socket., make total 120watt bright. 840lm each bulb. But the Amazon light says 17W(120W Equivalent) which is about the same I have, but since it is a LED light, would that be a lot brighter than now? I meant, don't expect significantly improvement, but at least better than now. Or how about 2x2ft square type fixture? since it is larger size even with same LED size inside, I am assuming it covers more area. My basement is 400 sq ft and has 3 that light fixtures on ceiling. And installation. I saw my ceiling light has 2 wires, white and black. But some of new model at Amazon has 3 wires, including yellow. Does it matter that I have to buy 2 wire light? Thanks.

Five years ago, I installed a three-way switch. I ran two three-stranded cables from each switch box, and then in my attic, I connected those in a junction box to a cable carrying power and to one running to the light. For the last five years, the switches have worked properly. Then they stopped working correctly, and I've run a bunch of tests trying to figure out what broke. I've replaced both switches and that didn't help. The attached picture shows the box in the attic: There are three wires running into the left side and one into the right side. The one on the right side goes to the light. The one on the bottom of the left side is the power. The black strand from the light goes to the black strand from the switch wire that runs to the top left. The black strand from the power runs to the black strand from the other switch (middle left). The white from the light connects to the white from the power. The two travelers connect to their corresponding traveler from the other switch. Here’s the clearest indication of the problem I’ve discovered: With the power on, I turn one switch on, and the light illuminates. I then flip the other switch, and the light stays on. I then turn off the power and go to the attic. If I take both black wires from the two switches out of their nuts and test them, there is [i]no [/i]continuity. This is bizarre. [b]If there’s no continuity, it means the switches are working properly together and should cause the light to turn off. But how is the power still flowing to the light?? [/b]If I manually disconnect the black wires and turn the power back on, then the light doesn’t work. But the light does work if the black wires are connected (one to the power source and one to the load) even though the black wires themselves don’t register continuity. Another way to explain this is through the grid below. This is how it behaves (if, in the attic, the reds are connected and the whites are connected): Switch A black and red continuous + Switch B black and white continuous = ON (This is the weird one. It should be off.) Switch A black and red continuous + Switch B black and red continuous = ON Switch A black and white continuous + Switch B black and white continuous = ON Switch A black and white continuous + Switch B black and red continuous = OFF Any guidance or ideas for further tests I can do to isolate the problem would be greatly appreciated!
