You can put extra bright lights in so you can see better cleaning, doing little projects etc but dim them down to a more normal room brightness most of the time. Also nice to dim the lights while watching tv or playing games

its the voltage mate. rheostat basically, designed for much larger voltages.

I burned out 5 capacitive touch sensor lights this week on LEDs, work fine with incandescent (if i didn't fry them first)

Some bulbs do work, I had the same problem had different bulbs and kept the one that worked.

Don't use LEDs in your house. The blue light hazard is significant, and they are electrically noisy (not as much as CFLs though)

[Anonymous No.1534606]

>>1534476
Some LED bulbs do work with dimmers but they're more expensive. Ones that don't work with dimmers have "DO NOT USE WITH DIMMERS" clearly written on them somewhere.

very simple you make the big light in the middle of the room bright enough to see in all the corners then you put in table or standing lamps with fancy shades and lower light warmer lamps to taste.
if you want to get hardcore about it you install special low current sockets in the wall near where the lamps will be and change your lightswitch to turn the big lamp and the small lamps on separately.

>>1534481
if you mean brood then lighs off. or ideally find a nice warm cupboard to hide in. if you mean breeding then you don't want a dimmer either unless you want a fucking argument about the correct amount of dimmness.
>>1534482
just turn the lights off, light from tv is enough to see where your cheesy snacks are and if your hands are clean enough to touch controllers.

>>1534574
dimmers are not rheostats a rheostat is an adjustable transformer while a dimmer usually clips the end off of the AC waveform with a diac or triac or some shit i cant remember but its not a voltage transformer.

>>1534596
>blue light hazard
? work on the same principle as cfl, except cfl uses uv to fluoresce the phosphor which is much more bad for you? so the choice between led and cfl you pick what? uv and noisy (and slow to warm up) over led? give me a break.

>>1535731
maybe he meant current? are leds too low current to work with old dimmers or something?

maybe its because of the capacitive voltage dropper in the led lamp, certainly it happens that e.g. hallway lights where there is more than one switch there can be enough current coupled between the strappers that a low power led lamp can parasitically draw a tiny current and when the capacitor inside has charged the led will briefly light, making the lamp flash briefly and dimly every few seconds or so, there are plenty of cases of that happening.

probably if you had a resistive element supplying the led there wouldn't be a problem.

A rheostat is a potentiometer, they are one and the same. Adjustable resistor, not transformer.

Conclusions
LED products are no more hazardous than other lighting technologies that have the same CCT. Furthermore, white-light products
used in general lighting service applications are not considered a
risk for blue light hazard according to current international standards. Sensitive individuals may have additional concerns, and
colored light sources—which may be classified as Risk Group 2 or
higher and require a label to meet accepted standards—should be
evaluated on a case-by-case basis

not all leds... there are a few tape stripes that have a driver you can use an incandescent dimmer or 0-10v style dimming on.

I only found that out 3-4 months ago when I installed about 150' of tape light.

It isn't any more of a hazard than any other light, anon. You'd need to be staring directly into the bulb to actually be harmed.

>electrically noisy

Christ, anon. Get ones that are not noisy or wire for 12v and keep the PSU in the utility closet. There's not a single thing that uses electric that isnt noisy in some fashion.

OP, there’s some bad info in this thread so we’re going to start from scratch. Unless your house has been untouched by an electrician since the 60s, Any dimmers you may have for incandescent lights are “leading edge” dimmers. They are cheap to make using either a single triac or a simple series of diacs and can easily handle very high wattage loads. The problem is the mains power is switched ON during peak voltage and in some circuits this drives a current spike, especially on low-load applications like LED lighting. Since the driver circuits inside LED bulbs themselves use a capacitive voltage dropper to smooth out the DC bus needed to drive the actual LED chips, this huge spike in current will quickly damage the control circuit.
Dimmers that day they’re capable of dimming dim-able CFL, LED, and traditional bulbs are called “trailing edge” because they switch on at zero crossing and turn off at the desired percentage of the way through the cycle. This means there’s no current spike, you can run them at very low load (like for LED lighting), and your bulbs’ driver circuits will be much more stable. They also typically run quieter at high loads than the leading edge counter parts. There’s no simple circuit or single component that does this for you though, and I THINK modern ones use FETs of some sort to control the timing and operate a power transistor - but I’d have to look that last part up so don’t quote me there.

TLDR: dimmable LED bulbs + LED (trailing edge) dimmer and you can dim to your hearts content. Though I will warn you, you can’t make LEDs dim allllll the way down to almost nothing like you can with incandescents.

Hope that helps.

Unless you intend to put it in a laboratory, about any kind of electrical device will not harm what is around it.

So, in a power system harmonics are very a real thing. The 3rd and 5th harmonics (180 and 300Hz respectively) generated by non-linear loads such as switch mode power supplies in computers for example can - in large numbers like that of an office building - have a measurable and very negative effect on the power system supplying the building. It essentially creates “load” on the transformer and lines feeding the system that older meters or protective devices can not detect, and makes delicate power supplies and motors run at very low efficiency. The other worry is that it makes your utility charge you more, which for the vast majority of customers is just not true. Even if it was, the cost difference would be <1% of the bill for the average house.
That being said, unless you’re doing something crazy like mining bitcoin in your basement on hundreds of machines, your house will literally NEVER reach a level of harmonic distortion capable of damaging home electronics.

The theory that these harmonics can, in some way, harm a human (that isn’t currently putting a fork in the socket) is truely asinine, tin foil hat level shit.

So, in OPs case, LEDs shouldn't be a problem, right?

[Anonymous No.1540010]

>>1539910
For the sake of being 100% accurate, LED lights and the dimmers used for LEDs do create some 3rd and 5th order harmonics. But even if you had dimmed LEDs lighting your entire house, and a dozen laptop chargers running all at once, the total load that creates is so small the voltage waveform you see at the outlet will be smooth enough for ANY consumer electronics. I’m grasping at straws to come up with an exception to this in a home... maybe if you’re an audiophile you would want some extra filtering on the input of your amps?

As kind of a side note to prove my point; pic related is the noise generated from a 100HP variable frequency drive running 1100 RPM (35Hz feed on a 60Hz supply) giving the mathematical maximum harmonic distortion of current. The wonky, rippled wave is the three phase current, and the mostly sinusoidal waves are the voltage. The voltage distortion is fairly minimal because the source is appropriately sized for the load. Same goes for your house: a very small amount of shitty non-linear load doesn’t have an effect on the overall 200A service for your home.

TLDR: LEDs are fine, don’t be a fudd. Leave your fear of the harmonic boogeyman to the real engineers.

Sorry, I got spun up and went off point. What OP needs is a dimmer that is designed to work on LEDs, and LEDs that are designed to work with dimmers. Just like I mentioned here >>1538899

I hope this is right. I thought some of the LED/CFL-compatible dimmers used pulse-width-modulation of a triac-like device, but when I tested mine it looked like a normal triac. Now I can see why.
