What kind of dimming is used, PWM or Voltage? Want to know if these lights would be good for filming (PWM is not good for filming).

I dont use any kind of dimmers, so I'm not sure if you could use dimmers with these lights. Honestly they are beautiful but kind of weak, dont you need very strong lights for filming? Anyways for the price they are perfect for lighting our garden.

Well when you dim an incandescent bulb, you decrease the voltage applied to the bulb. A linear Taper Potentiometer will do the job. Dimming an LED is a whole other ball game. With a PWM LED dimmer, the dimmer will actually turn the LED on an off at around 200 hz (faster than the eye can see it flashing). The length of time the LED is off versus when it is on determines how (bright) the LED appears to us to be. Doing this with an incandescent set up may not actually dim the bulb. Incandescent bulbs work by feeding electricity through a small wire that gets hot and glows (which is the light we see). Simply turning that current on and off so many times a second would not dim the glowing wire in the way you wish it would, I suspect.

These are for low-voltage only. they are not for use with high-voltage circuits. You should not have a problem because the lights do not have a photocell attached.

The only way you could dim these lights is to use a plug-in lamp dimmer ($10.00 from Home Depot with a 300 watt limit). I really do like these lights. I have them plugged in to a timer switch.

I used speaker wire light gets dimmer after halfway unless you attach wires to opposite end. But still bright enough to hurt yoir eyes if you stare at it.

LED's can be dimmed, and these should be able to be dimmed... but in my application they are either full power or off.

All I know is that is just plugs into a 110V. If you're using a lighting board, I'm guessing you're using for a theater? If so, you might want to look for a more powerful light. These are actually pretty cheap, but they work for VERY close range stuff.

Id recommend the 12 volt for optimum lighting. If you use a lower voltage your lighting will be dimmer.

These are not dimmable. Make sure the ones you buy say dimmable as a feature. If used with a dimming switch then they will flicker when turned on.

I have several of these units and have had no problems. I suggest you use a voltmeter to measure both the input voltage (should be about 12V) and the output voltage (voltage should go from about 0V to 12V as you adjust the knob from full dim to full bright. If no input voltage, check the power supply. If input voltage OK, but no output voltage, first check that you LEDs are working by connecting directly to the 12V power supply; If LEDs lite OK, dimmer is bad.

Just a standard incandescent dimmer by Lutron. Dv600pwh. Its a line voltage lamp, so low volt dimmers are necessary. You can also use DVCL dimmers by Lutron (recommended).

Mine do fine until you get to very low levels. Also seems to be sensitive to how quickly you move the dimmer- slower is better for avoiding a flicker.

Actually, there is an overload transformer. I hardwired mine by burying a plug inside the wall, but you should use the dimmer for 7$. It has 4 brightness settings and can be under mounted. Avoid direct wiring the lights, unless you've found a dimmer with a built in transformer. I already tried ;(

From my experience with these lamps, definitely not dim-able. I unknowingly installed three lamps on an toggle switch type electronic dimmer. Since I have surveillance cameras monitoring the illuminated area, we noticed after several hours of use (at approx 95% on) they started to flicker on off than just died. The vendor did replaced the " defective" lamps without issue. However, it wasn't until i installed the replacement lamps that I realized that the toggle switch was actually a dimmer and the people that turned the light on were inadvertently not turning them 'full on' causing the premature failure.

I have used 2 ILED lights on light stands for back lighting and I have seen no issue with flickering since they are led lights running on batteries. The battery life is dependent on the light intensity used. I have run both lights using the supplied Sony type batteries for over an hour without any problems. I have also used one light on my Sony HVRV1U HD camcorder. The light used in conjunction with the barn doors and diffuser produces a a soft light on the subject. Highly recommended.

I am using LED bulbs and am dimming them with the switch. So far, no problems and is working fine...make sure the bulbs state they are, in fact, dimmable.

Hi Sammie21,You should be able to turn them on/off by using the control on the camera cable, just roll the little wheel up or down to make the light brighter or dimmer.
