On all you AC adaptors - is the plug at the end male or female? - by John (Solon, OH)

Are they dimmable?

I'm looking to power a neon kit (4 tubes, originally for car underbody) in my bar and have burned up 4 AC-DC power supplies, the largest being 1000mA. I think the kit is drawing 3A and thats why they're burning up. Do you think your 3.25A transformer be sufficient?

if i am connecting 60 LED's in parallel, and conecting to 12 V 3.0Amp output power source. Is this ok.? - by sateesh (New Jersey)

I am wanting to use your 4-chip LEDs mounted in small flush mounted holes around mt patio, my question is that can I daisy chain them together with one power source on one end of the chain? If so, how far can I take it and still keep them all burning at their full output? Or would i need a junction box? If so how far from the junction box can the 4-chip LEDs be, my patio is approx 35 ft wide and I would like them to go from one side to the other every 2 to 3 feet or so. - by Wyatt (Dallas, Tx)

Is there an adapter that goes from the 3.5 amp transformer to the LEDs or do you cut the plug end and connect from there? - by Brandon (Houston, TX)

It says it works with 220v but it dont liiks like the pins fit in 220v outputs. Are there some converter including when buying it? - by Kenny

I have a mtx 200watt powered 12 inch car subwoofer & enclosure, what kind of power adaptor do I need to make this sub to work for indoor 110v? - by Wayne (San Gabriel CA)

I would like to be able to power my car stereo indoors some times. This is just the front end unit and no extra amps etc. How can I do this?

Do I have to buy an adapter and a junction box? I just wanna hook up some piranha bars in the bedroom - by Lloyd (Panama City, FL)

I'm putting 4 28" led strips in a cabinet, And i figured out that i will need 1.9 amps to power them, should i get the 2 amp 12v converter? and also will 4 strips connect to one transformer? Also i want to get the music controller, would 4 strips hook to 1 of those? - by Scott (Virginia)

I saw in the picture that this is a 100-240V adapter, is that correct? I'm currently living overseas and looking for one that will work for both 110V as well as 220V (the plug does not have to be different, I had adapters, I just need to know it is dual voltage). - by sabrina (adana, turkey)

Looking to use (2) 3 ft sections of the red LED strips. I want to use one power adapter for 110v use. Do you offer jumper cables to attach the two sections? also need to know which adapter to use. - by Greg (Portland, OR)

Would any of these adapters work to power an Inferno V1?

How long is the cable that comes with the adapter? Can you buy more? - by Don

are they water proof - by rich (yonkers ny)

Can lack of ventilation cause the switching adaptor to burn out? I made an uplight fixture using 11 feet of the flexible LED strip white which is rated at 200 mA per foot. The total draw is about 2400 mA or 2.4 AMPS. I used the Oznium switching adaptor rated at 3.25 AMPS. The transformer burned out after about 2 months of service, sometimes left on for a week.. The transformer was "hidden" inside the fixture canopy, with very little to no air circulation. And yes, the transformer plastic shows some warping due to heat. I plan to pierce the canopy opening up about 40% to allow for air flow. Do you think this is the answer?

The setup can be seen here:
