LED Question/Issue

[daygaragedreamer]

Hello,

Just finally got around to installing a bunch of LED lights I purchased from Bees Lighting several months ago and I think I am encountering an issue.

One side of the bulb has the sticker/label and along the sticker label is a darker bar that does not put out much light...

Well per the install directions and the label on the light strip N/L I am installing the light bulbs correctly...but one bulb on each strip has the label/bar facing out so it's not putting out as much light.

Please tell me I am missing something...

I would hope each bulb can be installed in a manner so that they are putting out all the light possible....

Please help!

You'll probably need to post some pictures for someone to really understand what your situation is.

Here is a pic. Hope this helps!

Looking at the pic you should see the right is good...but the left has the logo/bar.

When I put in the bulb so that the label is facing in...the light bulb does not work.

so, you're saying that the lamp only works when it's installed upside down, correct? IF that's the case, then something is wrong in the wiring.
Verify that your wiring is correct. I see incorrect wiring from the factories all the time.
Verify that you have non-shunted sockets.
Let us know if those two things seem correct.

You are missing something.

Switched the bulb housings. All is good now.

So I'm assuming this means the lamp holders were wired incorrectly?

Would be very interested in the answer to this question. I have installed 5 of these lights and plan to install 15 more. So far they have all been wired correctly, but they are cheap Chinese fixtures so who knows. Maybe user error?

Thanks, Cory

I had been eyeing some tubes that require the removal of the ballasts so the sockets are then just straight wired and thought that would be perfect as getting rid of another failure point will make the lights not only more reliable but maximize their efficiency too. Well I ended up getting a set from Costco and they not only require the ballasts stay in, they have to be the right kind and working correctly. I understand this from a convenience factor to the consumer who hasn't the ability or desire to rewire fixtures but one of my fixtures was over 20 years old and while it worked fine with the old fluorescent tubes, it was putting out hardly any light with the LED tubes. So having to replace a fluorescent fixture with the right kind of ballast so the new LED tubes could rectify the voltage coming in was overall a PITA. I did notice on one of the it looked similar to your problem, only it was still very bright, just pointing the wrong direction. It worked fine when pointed in either direction so possibly there is 1 advantage to these bulbs that require a working ballast to remain beyond marketing to those looking only for a plug and play upgrade requiring no wiring work.

My LED lights from Costco have a dark, translucent, almost opaque frosting to the plastic tube for maybe ninety degrees, that's evidently the side that is to be to the sheet metal housing for the fixture. I assume there is some reflective component to it, though LED's are directional light, individually.

The tubular plastic housing holding the LED array in an extruded plastic channel has multiple, kinda-oval punch-outs at each end, to locate and "accept" the LED-containing tubes, being placed onto/in-between the split end caps. These punch-outs do not appear to be offset-imdexed, so the plastic tube can only be inserted in one position. It's possible that the factory got them "clocked" into the retaining *******, off by say, ninety degrees, which would put the opaque strip on the tube, visible. Please note that I am referring to the Costco FEIT four foot complete luminaire/shop light, and not the replacement flourescent to LED bulbs like you have.

It sounds like switching the bulbs side-to-side aligned them for maximum light output.

I am mentioning the Costco whole-LED-luminaire issue because I got one that had three disconnected wires, rendering it unusable, until I disassembled it and discovered the loose wires, two of which were on the side where the end plate with the 120 volt cord attaches to the circuit board, and one where the 120 volt service into the PC board had a cold and imperfect solder joint, and was no-longer landed to the PC board, which just required a re-solder. One stab-in wire on each LED tube was un-landed, and hanging loose, so neither bulb would illuminate. Re-inserting the loose wires into the PC-board equivalent of a flourescent fixture "tombstone" for the pins on a flourescent bulb fixed that. I did the other 120 volt leg while I was in there, just as a good measure. Hey, maybe the Chinese tech was hungry for the fish-&-rice poke bowl they were serving that day when my luminaire came through the assembly line, just as the meal break was announced.

They were pre wired...so I guess so.

Happens ALL. THE. TIME.
