Hi i disasebled a little light trying to use it for a project but when i did it looks an awful lot like a uv led and im wondering if it could be one or if im just a safety freak? It looks a little less uv ish in real life
Probably not.
UV LEDs typically have a small, compact appearance and they are often encased in a small clear or opaque plastic lens or package.
The light they emit is invisible to the human eye, though it can appear as a faint glow if the surrounding materials or the LED itself are fluorescing.
Showing my age here, but i used a UV source to erase PIC ics.
The light is very purple (violet) looking.
Edit: My device manual warned looking into the light source could cause retinal damage.
Look like white light to me
That IC appears to have a LED driver circuit. Can you check the input voltage and current with your voltmeter?
Just as a comparison, I use high power white LEDs with a 500ma driver. The white light is so bright it is painful to look into.
This light is very strong but it looks like the uv bulbs we have used in pools but no cause for concern?
It looks like the uv light used in pools but i cant see why they would have uv leds to just turn it into normal light
where did you get it from?
The entire thing draws .2 amps at 12v and when i manually powered only one side of the led as seen in the violet photo it drew .1 amps at 8.7v. The driver is for converting ac to dc as they are g4 bulbs meant to replace low voltage glowbulbs
Normal electronics store i just removed the gel plastics
If that is the type driver I use, and if the LED forward voltage is around 1.5v, then the power would be around 2 watts.
Like I said earlier, if that LED is white, it would be way too bright to look into.
Just saying...
Yeah, that's what UV light usually do...
Yes, the LEDs are UV. That gel you removed contained phosphors that convert the UV into visible white light. This is how most white LEDs work: a UV led inside a blob of phosphor that converts the wavelengths into visible light.

Im not gonna stare into them much but uv can be harmful even when not staring at it too much. The leds are cennected in this way per side
So dont remove the gel coating if i want to use them as normal lights? Thing is i see the lught strongly even when the coating is gone
The exception is RGB LEDs. When they emit "white" light, it's not really white at all. It's 3 distinct wavelengths (red, green and blue) which fool the eye into seeing white.
If you want to use them as white lights, keep the gel in place.
Perhaps it isn't all gone, maybe traces remain.
But even UV LEDs are visible to the eye because they don't emit a pure single wavelength. Most of the light is in a very narrow range of wavelengths in the UV part of the spectrum, but a little of the light is outside that range and some of that strays into the visible spectrum we can see.
So more or less dont mess with the coating and il be fine and my eyes wont be damaged?
It a WHITE G4 bulb NOT UV
Yes but when i remove the yellow coating ut looks exactly like a uv bulb we use for the pool
