I just installed it today, but the bulb wont glow. How to test if the bulbs are defective without affecting eyes?

unplug the fixture. check circuit. if power then check recepticle with known good light fixture of any kind. do not touch bulb with fingers and make sure connection is good between bulb and plug in holder. then plug back into base. if still no light. try new bulb. if still no joy, problem is either in base unit or wiring to the base unit. hope this helps.

I've noticed mine does not start up very well. Twist the bulb as if removing and then reinstall. It won't start immediately. Also, the indicator is not an LED like it looks, just a lens to the inside. Turn of the lights or shield ambient light, it might be on, you just can see it.

make sure you have power at the plug and the bulb is in the socket and secure.

You should be able to see a coiled filament at the connector end of each tube. If there is a break in either filament, the bulb is defective. If you have access to an ohmmeter, that allow for a better test. You should measure from 4 to 5 ohms across each filament. If you get these results, check to be sure the bulb is completely seated in the holder and that the holder is properly fitted into the lamp (turned 1/4 turn clockwise after pushing into the lamp).

i replaced mine and didn't have any issues (smell) . Is it still smelling? You may have a more serious problem. I would remove the newly installed bulb assemble, inspect, and start again.

Yes, I wondered the same thing when I took the bulb out to remove the packaging around it. It seems to work fine. I took the bulb out of one of my other blacklights and it does the same thing, so maybe it's normal.

I tested mine by going into a normal lit room, turn it on, then turn out the lights in the room, making it dark and then seeing if the light came on. That is how I tested it and it worked exactly as it should.

I would return the bulb to the store or online retailer. Zoomed's products should not make noise when you turn them on. This is just a bad bulb.

When the unit is working the light is very faint, but it is also possible that the bulb has blown or the unit isn't working. I would try putting it in the tank, turn off all the lights, and then see if the light is on at all. If it isn't you could try returning the unit, contacting the company, or just buying a new bulb to see if it was just the bulb. I have been using this for a while without any problems. Also, you will only see the blue light in the little circle at the bottom in the front when the unit is plugged in and workign properly. Hope this helps a little! Good luck!

You have to make sure you screw the light bulb on right if not it will not work. I had the same issue.

Remove the cover with the palm of your hand (twist counter clockwise).Unscrew the little bulb and replave with a similar type. Put the cover back on. Note: at least your lights work; mine I'm still figuring out why they don't light up!)

Sounds like yours is either faulty or doesn't have the right bulb installed. Mine is super sensitive and I barely have to brush it for it to change levels and turn on and off.

It sounds like either a bad connection, or there's a problem with the rheostat. I would unplug the unit, remove the bulb and try to reseat it. If that doesn't work, try a different bulb. If that doesn't work, try leaving the light on at half strength and see what happens.

Try 2 things: Check the switches on the light to make sure they are in the on position. Check the light bulb.

This unit is sold with lower quality bulbs, in fact one of my bulbs was not working ....did you try the other (included) bulb?

Try changing the bulbs with standard bulbs. The bulbs that came with the lamp have a blinking mechanism built into them.

Mine did not work. Also the wattage capacity is reduced when the bulb is pointed down for some reason. Buy the Phillips combination light/sensor

I believe you have a defective light. I love mine. It only has on and off features.

I don't mean to be rude but you are testing it in the dark? And it doesn't glow? If so I would contact Amazon if you bought it from them and get your money back. It worked great on my items so I'm thinking you must have a defective can.my items
