Bumper w/Fog Holes - Light Leakage

It's hard to put this into words, which I guess is why it's hard to find an answer when searching. I'm ready to get a front bumper and I'm down to a couple choices. The Poison Spyder Brawler Lite is one choice and I see that their fog light holes have tubes welded onto the back of the holes so the lights will flush mount onto the rear end of the tube. Theoretically, this will ensure all of the light exits the front of the hole instead of lighting up the back of the bumper.

Many bumpers simply add mount tabs behind the simple fog holes cut into the the front face of the bumper. Given most angular edges of bumpers, usually some parts of the light's circumference will sit fairly flush, while other parts will have a gap between the light and the bumper. Theoretically you might lose light out front and instead light up the area behind/under the bumper.

Is this a common issue? If so, how big of a deal is this? For comparison, the JCR Dagger Stubby would be another choice (and it doesn't have the mounting tubes).

Any reason to be concerned about this?

Thanks

Kinda sums me up I'd say! Well, I am an engineer after all.

But, after I thought about the possible issue, I did see that Poison Spyder addresses the concern on their site in their "design advantages" descriptions pertaining to that bumper . They note that this is why they added the tubes behind their fog light holes. So I can't be the first to think about this. Hmmmmm....

Jerry, see if this calms your sleepless nights:

The light "leaking" was exiting the lamp housing at a near-useless angle, and probably would have ended up at a location and angle that did you no good if it had not leaked into your bumper (perhaps causing death wobble).

If you made a containment tube out of super-shiny unobtanium, the light exiting the lamp housing at a near-useless angle would bounce once or twice off said super-shiny unobtanium tube with zero light loss and probably still end up at a location and angle that does you no good.

While the light is now outside the bumper, there's a good chance you gain nothing from herding it through the gate if it's just gonna' sit in a corner of the pasture and lick its balls.

Being that I'm married to an engineer turned wildlife biologist, I understand your angst. He turned his lightubes into coldair supply...

This is true, and then there's the fog light liquid level sensor problem that Jeep never fixed. At 35% liquid level the light back scatter refraction worsened which had an extreme adverse effect on the forward light progression angle and lessened the lumen intensity by 28%. The industry standard 37-1/2 degree bevel on the tube backside helped somewhat.

Honestly... I had the Brawler Lite with Fogs, pretty much no difference from the stock fog lights as faar as output even thoughh they are a little more recessed

I then swapped t a BFH and scrapped the fog lights, although once in a great while I will wish that I had some fogs mounted at bumper height I can count one one hand in two years where I said I wish I had some.

go with what bumer design is most appealing to you, and disregard and details regarding light leakage... pick the best bumper that has fog lights and be done with it

Ok Jerry, try this. Comes from a mustang forum, might give you an idea. Being that I'm married to an engineer turned wildlife biologist, I understand your angst. He turned his lightubes into coldair supply... DIY or a Rough Country hybrid bumper...a little over $300.
