Does this work for flourescent tubes with ballasts? Does the tube have to be plugged into the ballast?

  • Absolutely, the tubes do not need to be plugged in, just touch the end of the lamp to test.

    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.

    It's a cheap tube tester. Works OK just have to hold it on the bulb for a few seconds as it pulses current as opposed to a steady stream. Will light up t5 lamps to t12's and neon of all sizes and colors. does not light whole piece just the sections near the tip of the antenna. Battery lasts for a decent time too. Havent broken the antenna yet but I would buy this again.
