1 out of 5 eggsJunk?

Pros: None

Cons: It broke

Other Thoughts: It worked for a little while. Not worth sending back since the price of shipping would be the exact price of the product.

4 out of 5 eggsNice lights for the price

Pros: -Nice vibrant color
-Good price, got 2 of these for 11.99
-Decent size
-Very easy to install, you need little to no computer knowledge to install these

Cons: The only thing i could think of is that the velcro attachments that they are shipped with are pretty bad, at least inside my case. Do yourself and just get some double sided picture mounting tape, works great.

3 out of 5 eggsMore like orange

Pros: 1. They work as they should

Cons: 1. They don't emit that bright
2. Didn't expect it to be so small

Other Thoughts: I don't think I need this cause it's too small and they are not bright enough. If you are looking for a not so bright this is for you

4 out of 5 eggsAmazing brightness

Pros: Very bright and visible through my case window. This product is very easy to install and I had no problems with the placement of the lights because of size.

Cons: The light outside of my case is a tad orange, but inside my case it seems more red. Velcro is not very strong I would recommend some double sided tape. Also, the converter looks extremely gaudy and isn't very easy to hide.

4 out of 5 eggsGood Lights, Bad Parts

Pros: I own 3 of these which I used to back light the mesh covering the 5.25" drive bays that I am not using/converted to 3.5" hard drive bays. They are great lights, very bright, and I typically leave them on 24/7.
Also, mine are a proper shade of red, and don't look orange like some reviews have mentioned.

Cons: Like lots of people have said, the parts and adhesive for the Velcro are a bit shoddy. I personally used super glue to get the Velcro to stick, after it fell off the case/lights 4 or 5 times.
At one point one of the lights started to fall out of the tube that it was in, but I just kinda pushed it back in and haven't had a problem since.

Other Thoughts: Since you can only attach two of these lights to an adapter, I was stuck with having to have two adapters in my case (which is OK), but I didn't want to have two of my expansion slots taken up by the switches, so I used electrical tape and wire cutters/strippers to attach both adapters to one switch (which works great). I wish there was an /easy/ way to wire these into the case switch that controls the LED for my fan though.

4 out of 5 eggsA tad orange, but tolerable.

Pros: I have prior purchases through newegg with Logisys for their cold cathodes and they are good.
Decent quality. low priced.
Wanted A 4 inch cathode for between my power supply and my dvd-rom drive. perfect fit for this area of my case.
It is A bright cathode.

Cons: A bit on the orange side. Then is still mid-afternoon as I post this..(only reason it got 4 eggs.)
I knew from my prior purchase of this brand's cathodes..the mounting they provide is inadequate.
(hint on mounting in other notes)

Other Thoughts: I own the 8 inch green cold cathodes (two pack) made by this same company..and they are VERY GREEN and VERY BRIGHT..they cost the same as this solo 4 inch bulb. but this is what I wanted for the spot. and of course I knew the price on both prior to picking this up.
oddly enough..there is A breakout box for this like the green dual set. with 2 outputs. IT IS NOT sound activated. (knew that aswell as soon as i seen it)
But that isn't A problem either. less to break imo..

Be sure to clean the case where you plan on mounting the velcro with rubbing alcohol prior to installing these.
(make sure it is dry of course
Also,leave the 2 pieces (rough and soft) attached to each other. attach it to your bulb..and directly into the case.. had better luck with it staying attached to case that way.
or..could avoid all of that..and get some good dual backed tape or velcro of a better quality. or just use wire ties.

3 out of 5 eggs

Pros: Very bright.
Very easy to hook up, even for those that are not tech-savvy.

Cons: Slightly orange-ish.

The adhesive on the velcro strips does not hold up well to heat. I originally had the cathode and box attached, upside-down, to the top of the case. They both fell and were in contact with other components. I was baffled when one morning my computer was blue screening.

I ended up moving them elsewhere. I put the box on the inside of my optical drive bay. I put the cathode on the motherboard tray. The cathode's adhesive melted off and dripped down to the bottom of the case. I guess I should have thought of that. My temps only reach about 50 C, so this shouldn't be a problem.

Other Thoughts: You get what you pay for. This didn't cost me much, so I can't be too upset.

5 out of 5 eggs

Pros: bright,

Cons: parts are cheap, so be careful while installing so you dont risk breaking/snaping something.

Other Thoughts: i dont see why newegg would sell this one for the same price as getting "two" 12" cathodes?????
