Battery powered led lights

Battery

Know you need a spotlight but can't decide which would be best? Or maybe you aren't sure whether a night light is a better choice than a step light? Add critical lighting to an indoor or outdoor darkened area quickly and easily using a battery powered light fixture - no electrical outlet needed. Battery operated lighting offers many different types of uses with energy-efficient LEDs that are powered by either lithium-ion, lithium coin, AAA, AA, C, or D batteries.

Is my family the only one that used 100w bulbs in lamps? Because 60w(equivalent) is not enough for me, and I?m getting sick of it. I know the CFLs had 100w but they were huge, why aren?t there 100w equivalent LEDs?

@rhenryb4 I started adding brighter lights to rooms a few years ago. It turned out my vision was getting worse. More light gave text more contrast.?

I have had reliability issues with the cree bulbs. They seem to fail fast.

  • Reply

@fadamsb6 That would seem to be the exception. It?s a popular bulb, certainly the best I have used. How many failed?

  • Reply

@fadamsb6 My first LED bulb purchase was the new(er) Cree 4Flow style

  • Reply

@shudsonb8 Absolutely love them, though I understand their warranty is shorter than the one on the standard model.

Wish I had known the difference between LED and CFL when I redecorated and bought about 6 CFLS for my upstairs lamps

@jdavisba ?the dimming drives me nuts, and my luck these will last for years.

@twoodsbb I did the same thing, but couldn?t stand the gradual warming feature, to used to the instant on. I replaced all my CFL with LED bulbs and am slowly getting rid of the rest of my incandescants.

I have tried many different kinds, and the Cree is our favorite. When it?s installed, you cannot even tell that it?s a LED

@lgordonbd it glows exactly like an incandescent.

  • Reply

@lgordonbd If you want to keep the incandescent look, the Cree will not let you down at all.

  • Reply

@pperkinsbf ?Plus, the Cree is one of very few that are OK to install inside an enclosed fixture

  • Reply

@pperkinsbf I?ve been using the Cree bulbs, many in enclosed fixtures but also in open space, for a few years and have not encountered a single failure.

  • Reply

@bdixonbg ?I think this is because of how the LED chips are faced, inside the bulb.

?Be careful what you buy and check the packaging.

@tbakerbj I bought a lot of Feit Electric bulbs on sale, and most of them have failed.

  • Reply

@tbakerbj ?I?ve also had some Feit Electric bulbs fail within the first 15 minutes of being used, right out of the package!?

@etaylorbl ?I refuse to buy any more of their products, they are all garbage from my experience.

@etaylorbl I?ll take the dirt cheap kind, thank you!

My hubby hates that I?ve switched to the fluorescent from incandescent because they take a couple minutes to become fully bright. Is that the case with the LED too??

  • Reply

@mgrantbo Does 1 or 2 watts actually make an impact??

  • Reply

@jhallbp Nope, LED are full brightness instantly.

  • Reply

@jhallbp The thing I love about LEDs is that there?s no filament to suddenly break. Statistically, LED bulbs should last 15+ years, which is long enough to pay themselves off.

The best way is to first figure out the current need of the LED, and then use Ohm's Law to calculate the resistor value.

  • Reply

@jlopezbs Typically, you will want some margin to ensure that the LED receives enough current, so you will need to go a little lower than the theoretical maximum value.

  • Reply

@jlopezbs Most mass market resistors are not very precise and their actual values vary from 1% to 10% of the value indicated on their packaging, so you will need a margin of safety. For the above example, I would probably use a 220-270 ohm resistor.

  • Reply

Just in case you are wondering, no resistor in the circuit or a resistor with very little resistance will likely cause your LED to burn out quickly because you will be feeding too much current into it.

  • Reply

@mcarpenterbv Think of it as a circuit breaker.

  • Reply

@mcarpenterbv I hope this helps those hobbyists who need a general working method.?

  • Reply

Instead of a resister, can LEDs just be added on to the output end of the standard bulb??

  • Reply

@tholmesby No, because the voltage drop from the bulb won't be low enough and burn the LED out. Resistor is the best way to go. 10 ohm resisters are the safest resisters to use.?

@ccollinsbz hey my switch has only 1 wire?

  • Reply

@telliottc0 I have never seen a switch with one wire could it be possible your switch had 3 wires but broke off

  • Reply

finally i found something
