Portable Handheld Neon Tube Lamp Fluorescent LED Tester

Works great found all the bad lights and good lights. Doesn't test the ignitors just the bulb gas, is the only downfall.

Press the button to energize the tool, touch the neon bulb with the antenna, and if the gas charge inside that segment of the fixture is intact, then the neon light will illuminate for a short distance around the test point. If it doesn't, then the neon segment is damaged / defective.

Does the job but very simplistic.

Works good the need to add case fore

Don’t hold the shock button while the antenna is touching your finger. You will not feel it shock you, and you will LITERALLY burn your flesh. The worst part is your finger will smell like burnt flesh for hours.

It device to produce high voltage pulse, this device commonly used to check neon light tubing.I recommend it to sign maker or to Electrician works on neon lights.

Works will in my shop.

Works well

Used it with Science First Neon Wand and it worked great.

Works as good or better than my old one that I paid ten times this price.

Great price! Cool gadget and very useful when dealing with flurecent bulbs.

works good

It works perfect. I have neon signs and when something goes out, I just pull out my Docooler neon and checker and find out whether its is the neon or the connection. It has not failed me yet.

Works great will buy again.

I acquired two rare Converse Chuck Taylor neon signs and I was hesitant to order new transformers for them because the sign would not light or flicker when plugged in. I was in search of a tester to see if I could confirm that the neon was functional. Most testers on the market are quite pricey and I was not looking to invest a lot to confirm the neon before ordering expensive transformers each over $100. So I decided to take a chance on the Docooler portable handheld neon tester for like $12 with free prime shipping. I received the unit and its a pretty basic yet solid unit especially for short money. So since I got the signs for free I am now into the project for $12 or so before committing to more money.The instructions are pretty basic but then again so is the unit. The one thing you need to do is put the batteries in minding the polarity. The unit takes 4 AA batteries and the polarity is marked with a tiny plus and minus on the inside of the slide off battery compartment lid (easily missed if you don't know to look for it). So don't be fooled it may take 4 AA batteries but the unit is producing some serious voltage do not touch the output antenna you will get shocked. The operation is pretty simple once the batteries are in extend the antenna portion of the device and press and hold the power button. When you push the button the little LED will light indicating the unit is working. Next step was to test it out on the sign itself. All you have to to is touch the tip of the antenna to the neon glass tubing and press and hold the button. Now mind you that this is a handheld unit driven by 4 AA batteries so the whole thing will not light up because it does not have the juice of a plug in model but it is a fraction of the cost. I was able to get all the sections of my lights to come on and flicker indicating that the neon was still present, so I now have the neon sign transformers on order. As a side note I tested the Docooler on a CFL bulb and a regular florescent both of which glowed showing they were ok. So my two cents is the Docooler portable neon tester is an inexpensive and handy tool for someone who sporadically deals with gas bulbs as a way to test the ones that are not working to differentiate between a bad ballast/transformer and the bulb itself.

Works great. Good value for the money. Get's basic lighting of neon so you can tell if tube is functional.
