Is there any difference in the energy savings of the various brands of energy efficient light bulbs?

I just finished converting every light bulb in my house to the new energy efficient bulbs. I did it with a combination of GE, Sylvania, and Walgreens house brand. I’m just wondering if there is any difference in the life or energy savings between the brands. I have noticed that the 13 watt (replaced 60 watt) Walgreens brand gives off a white light, which I prefer, while the GE gives off a yellow light. Why is that?

Is it possible to “warm up” the light on LED landscape lighting?

I’m considering replacing my halogen landscape lighting with LED but worry the light will be too blue/white. I prefer the warm, soft white of the halogens, but like how energy efficient the LED bulbs are. Is there a way I could filter the LED bulbs to make them light less blue/white? Perhaps there’s some sort of colored, transparent film to put over the bulb that someone could suggest?

Solar Powered Torch Circuit?

Hello, I have a project for Engineering, I am required to obtain a circuit containing a solar panel. Because I can’t buy the raw cicuit, I need to buy an object that contains a circuit, with wires, solar panel, resistor, diode – just basic things like these.

Remember it has to be a circuit with the wires etc, not a microchip with everything on there.

If I took this apart, opened it up etc, would I get a the kind of circuit I’m looking for?

How do I convert 110 out door path light fixture to low voltage or LED?

I have about a dozen 110 “mushroom” fixturesin my garage (one of those projects that never got done) and two spot lights. I’d like to convert them to LED or low voltage. Does anyone know of any adaptors that will do the job simply without tearing out the wiring, like maybe a screw in base? I’m not very familiar w/electrical fixtures bit since I have invested over $400 in these things, and they are just taking up space in my garage, does anyone have a suggestion? Manufacturer, where to buy etc.
Thanks in advance for your help.

Buying a table saw on a budget?

Dear fellow woodworking enthusiasts, I am using an old shopsmith for a table saw right now, but it’s starting to fall apart, and it’s end is near. I am looking to buy a new table saw, but I am on a budget and could probably only afford something in the $400-$500 range. I’ll be using it for building small to medium sized projects, using mostly hardwoods. I would like to buy a cabinet saw but they seem way too expensive. Are there benchtop or contractor saws that will work well for cutting hardwoods? Also, the idea of buying a used cabinet saw has passed my mind. I’m just afraid I don’t know what to check for when looking at a used saw, and I could be getting one thats no good. I’m not looking for the worlds best saw, just one that will work well enough to get the job done right.
Thanks for all your advice
