I have noticed this with my own build, I have CCFL that really light up my green antifreeze, but I also have UV LED's on my build, that do not seem to get the antifreeze to glow as well as the CCFL does. so my answer to this question, is that it is the type of lighting being used that is causing the issue.

now that is supposed to be all black lighting or UV lighting, but as you can see when compared to the CCFL, the LED black lights or UV lights, look almost blue.

LEDs produce far less UV reaction than other sources. Some mfg have stated that "UV" is the color designation and that the bulbs are not UV emitting.

Yeah....the little girl hentai avatar is really creeping me out....

Yup it takes rather expensive LEDs to push up into the UV spectrum and then they age themselves. I have a very expensive flashlight with 6 UV LEDs of two different wavelengths leak detection. Most UV LEDs are purple colour.


CCFL is actually the most efficient means of UV light production.

You need a UV CCFL lamp.
UV LEDs are a scam since UV is just a colour for them unless your paying $60 for a UV LED cob which is still only 1/4 the strenth of a cheap CCFL.

Is there actually a good quality UV CCFL option for PC use? The cheap ones are notoriously unreliable, hence LEDs have jumped in, but they're not proper UV.

I don't think I'd even mind paying a lot for one, as long as it did the job properly! LED's generally aren't much good, although the Darkside ones worked out OK for me... I definitely got a good UV reaction from the Mayhems fluid I used, but it faded by a good 50% or so within a couple of weeks. I think the UV component of the fluid itself does break down though, so you'll never get that same 'wow' factor you get when it first reacts. So regardless if LED UV ages or not, you'll still see some degradation in the effect even with a top quality CCFL.

I have the same CCFL lighting and the controllers that come with them are very cheap and can cause the lights to pop. I would suggest a better controller for those lights. I use a fan/CCFL controller with my setup. there are lots of good options for controlling those lights.

http://www.performance-pcs.com/g-van...er-silver.html

now, if you decide to get one of these controllers, the reason they are so cheap, is that there is a manufacture defect with these controllers. the circuit board will ground to the frame of the controller, so removing the metal mounting screws, and replacing them with plastic screws, then adding plastic washers will fix the issue with this controller.
