How much energy do these bulbs use in comparison to LED blubs?

I would say a lot more. A 40W equivalent LED bulb ranges from consuming anywhere from 5W - 7W. That's about 8x more consumed power.

40W is the maximum. However, if you use LEDs, you can only consume 5W from the 25W incandescent equivalent. It works great for me. Love the light.

We noticed an increase in the brightness of our fixtures after we replaced the halogens with the LEDs. We had been using 20W halogen bulbs. As a result, I cannot say how well they match a 40W. The fixtures run much cooler now which is a plus.

I am sorry that I, as an ordinary consumer/user, do not have A QUANTATIVE ANSWER for your question. However, by comparing this 'new LED' light bulb to the 4-WATT 'old incandescent' light bulbs we used before, its light output is BRIGHTER AND WHITER. I hope you are satisfied with MY QUALITATIVE ANSWER.

For LED RGB light, the color temperature of the white is about 6000K to 7000K. Compare to a 12W halogen light bulb, which has about 2800K to 3000K, LED light bulb has 3000K to 4000K difference in temperature.

Try searching for Amazon. I am sure you can find the same blubs or even better ones. I use really bright LED light bulbs because they use less heat, and energy.

I've read somewhere they output 1200 Lumens with power at 22 W. More or less it compares with a 75W incandescent according to some charts. This doesn't take efficiency into account. I'd say a bit more than 75 after having had those for about a year. HTH.

It is supposed to put out an equivalent amount of light as a 50W incandescent blub, but with much less heat. So it is more efficient. Same light as 50W incandescent bulb using much less power.

The power consumption of leds are miniscule. You really won't notice any increase in battery life.

I really do not know. I do know they use LED's which are very bright and use little energy. I could not be happier with mine. Very reasonable price. Have had no problems.

The MR16 LED listed is 320 lumens which is equivalent to what I was replacing as a 50W halogen. The difference is that the LED is more focused as a light beam and was brighter on my display floor that the halogen bulb. So overall, I saved a lot of energy and heat. More importantly, I was able to buy a few more track light fixtures and added two more LED bulbs for a much even/better light distribution on the floor area for the retail store. I hope that helps.

I don't really know. They are at least equivalent to the bulbs we removed, but these use much less power.

we used GE Reveal Halogen. This bulb uses 53 watts, replaces 75 watt bulb and has 790 lumens. Uses 28% less energy. We love it.

I use these LED bulbs (http://www.amazon.com/G7-Power-Boulder-Lumen-2-Pack/dp/B00CRHG63Y). They work well with the lamp and are very energy efficient.

It's your call, this LED lamp is very bright but will never reach the same level as a halogen lamp, but if ambient heating from halogen + higher electrical expenses are not as important as brightness, stick to the halogen. With LED you get a good result, less ambient heating, probably higher bulb lifetime and you will spend 8 times less for energy with light. The big difference between both is the spreading of the light beam.

I use a 60W equivalent LED bulb and it's been working great. It doesn't heat up or anything so I'd really recommend it. Plus, the bulb's brightness is sufficient but very relaxing for the eyes, at the same time.

We use energy saving bulbs so no complaints about any excess heat. Don't know about LED bulbs.
