My $14 bug zapper has helped kill a lot of small flying insects indoors, but the UV bulbs are notorious for burning out.
Either that or they require replacement every year anyhow. Mine lasted a few month less than a year.
I took it apart and got zapped... Should have known it would! It uses capacitors to double voltage which stays hot.
The bulb was flickering and soon died altogether so I decided to use UV LED's instead.
I bought a 15 foot reel of them on Amazon for $13 and they arrived today:
The 12 volt spool uses almost one amp as tested on my supply.
LED spools can be cut where marked to make shorter strings and connectors can be added:
Each scissor mark has gold contacts marked + or - for connections. The tape cannot do sharp corners!Don't forget to buy connectors for smaller lengths!
Here is a strip of 9 LED's cut close to the length of the UV light bulb. I plan to tape one on 4 sides of the dead bulb:
The current is only 40 milliamps for each string I'll use.
Waterproof LED's require that the clear coating be stripped off at the gold dots for the connectors .
I used a razor knife to cut down carefully and peel the covering off carefully!
Connectors unsnap from one side and the gold dots must be placed onto the metal prongs inside.Make sure that the red side goes to + and black to - or you may get the wiring wrong!
Only one end of the connector will work correctly. The other end can connect to more if needed.
I chose to cut the wires on my first one as a test string for a quick test of the UV LED effectiveness:
I hung the string behind the zapper to see how it works first as it still kills bugs.
Here it is with just one string of 9 LED's hanging behind it. Plenty bright!
May just need 2 strings or it will become a nuisance.
Saturday morning I found 3 small bugs in the high voltage wires.
If it does any good, I will make a supply for 12 volts using a capacitor from 120 volts.
