Headlamp issues

Postby diamondback0320 » Tue May 14, 2019 12:11 pm

For those still running the 100w aircraft landing 4509 bulb what kind of plug are y'all using on the cord? I've always run this bulb because I like the distance I get but every plug I've used from cigarette plugs which seem to get too hot to a regular house receptacle etc and keep having issues with the bulbs blowing bout every 4-5 trips.. I'm speculating bad ground but I've tried several different ways on that too..my rigging is all DB aluminum.. getting pretty expensive at $10-12 a bulb.. anyone else run into this problem & solved the issues..thanks

You may have to direct ground to the battery just for the light..

I got a good laugh at this post... had a buddy sort of fall asleep frogging one night with that light on. He burned thru his hair down to the scalp before he woke up. Sounds like a bad ground to me but im an electrical dummy. Put an inline fuse next time see what that does.

One thing that is always overlooked and im guilty as well is making sure the clips are clean,maybe sand them scratch em up clean the terminals good and spray that red stuff on them...sometimes its all about claning stuff up, even the contact point on the bulb and headlamp

Biggest thing with the 4509 is not to let it get shocked around by just tossing it in the storage box, it needs to be treated like a sore peter, don't beat it, the filament is very fragile, there is a spot similar to it that is more resistant to damage. I don't recall the #

Gotcha... been using this bulb for years and so did my dad 70's - 80's before he passed I don't remember him having to replace nearly as much

Any recommendations for a light that's equivalent.. seen a couple that friends have & haven't really been impressed as far as brightness but definitely lighter by weight

Bad connections won’t cause the problem described, they would limit the voltage, making it run dim, cool and last forever. Those lamps are only rated for 25 hours at 13 volts. Run them at higher volts and they are cooking. The bulb should draw 8-9 amps, which should be fine on a 15 amp AC type plug, so overheated plug is a clue. Hot plugs are making resistance, dropping voltage to the bulb, but it does not sound like enough.

Check your alternator voltage at running speed. You may have a bad alternator or voltage regulator. First guess is you are running a single wire alternator setup, that is overcharging the battery.

All new motor & alternator..gauge shows bout 13.5 volts running.. using probably 14gauge wire from ext.cord

Ordered a new bulb..went with the q4509..100hr life span instead of the 25hr & heavier filament & gonna wire direct to the battery & see if that solves the issue

Just like Fenner said, be very careful with the storage, especially when it's hot, that filament is very sensitive to vibration. make sure all connections are secure. A slightly loose connection will create extra heat, thereby reducing lifespan.

My lights all use a 2 wire extension cord maybe 14 but probably 16 gauge. Use a regular house hold 29 amp receptical. I have used all sorts of lights and always came back to 4509 for the same reason that it throws farther. Right now I am using a 4509 LED replacement and I like it. It throws light almost as far as a regular 4509 but not quite. It is good enough That I am staying with it. It seems to light up the frog better with the belly really standing out. Their eyes light up better in the needle grass. I have dropped it a few times with it bouncing off the deck with no ill effects.I even dropped it overboard once with it lit and no problem. The down side is it is heavier than regular bulb by 5 oz.

Bad connections can cause excessive resistance just like a bad socket would. I would run a new socket with independent power and ground direct to the battery or a fuse panel. Clean all connections with contact cleaner and apply dielectric grease prior to reconnecting.

It wouldn't hurt to check the voltage regulator as Sliding gator mentioned. Many of The older 1 wire alternators have voltage regulators that can be replaced, and are not to expensive.

Good luck

I thought about the led 4509 also but like you said it is little heavier so haven't tried it
