I'm installing lights in a camper van and for aesthetic reasons, insist on my recessed ceiling lights having gold/brass trim. The problem is, they don't appear to make those for 12V systems (at least within my budget). Is it possible to run something like this on 12VDC? Important to note that...
Hello there,
I'm currently trying to get a massive greatsword to light up using an LED array that goes up the blade controlled by a hold button. This isn't my first lighting project, but it is my most ambitious so far. I'm in the pre-prototype phase right now. I'm still trying to work things...
Hi, I'm trying to fix a center light dmx CTL-6 of 250w by ACME. The problem was that the light didn't turn on. I opened it and found that the bulb had white spots so I thought it didn´t work. But before buying another bulb I checked the supply voltage noticing that it had 220v. I looked for the...
I have a little experience with wiring after having to hot-wire my aftermarket radio in my car when changing it out, however I do not know how to fix this issue. The wires in the plug were loose and the lights were not turning on because of this, so i cut it off and figured it'd be as simple as...
Hey everyone,
Hoping someone can help me out with this. I have a church that has an 8 scene programmable lighting switch (Leviton 408CP Luma-net Remote Memory Control Panel) but either they no longer sell these or they are literally out of stock everywhere.
I was wondering what I could replace...

So I have an cheap old plastic SMD LED desk lamp but its battery and circuit board are missing. I want to turn it into a USB powered lamp for my new apartment but I'm not sure of the best way to power it. It has 31 LEDs and the label on the...
Hi,
I recently had a fault occurring whilst connecting my laptop to my mixing desk whilst having multiple new DMX fixtures connected to a USB interface. Whilst checking for faults I discovered a voltage of about 80-90V between the DMX port on the fixture and the Earth Connector. Knowing that the...
So not really a -homework- question,apologies, but i feel its so basic it might's well be and would seem out of place/ too basic for any other categories...
I like to fiddle around and my latest interest is adding lights to crafting projects.
I had a few "flame effect" light bulbs i wanted to...
I am in the process of building an automated lighting system for a bathroom in my home. The goal is to have the string of light turned on when the bathroom door is closed and nobody is in the room, and then have the lights turn off when someone enters the room. I want to have 3 failsafe's to...

2 generators are connected to the bus below.
Given
V1 = 300V, 50Hz
V2 = 400V, 60Hz
When the switch is opened, calculate
i) the maximum and minimum voltage across both light 1 and 2.
ii) peak voltage across both lights
iii) maximum number of light pulsation
How do I solve the issue above? Any...
so I took the LED strip out of my tv or to be more accurate 3 LED strips (6 bulbs each) I thought if I took a strip down to 4 I could hook it up to 12v power and it would light but I have gotten nothing, anyone willing to help me figure how to power these?
Hello AAC!
Running into some issues with my current light switch design, and realizing that, if possible, I would like to change my setup to include some sort of sensor that can detect movement. Basically, my application for this bedroom light would be to have the light turn on and off based on...
