Are my Barnburner bulbs bad? Old?

[djans1397]

Hi All,

I have a few BB Fatboy bulbs that I just received that are giving me a funky beam with dicolored tint. The beam has a small wedge shaped brownish tint to it. Really weird I thought, so I inspected the bulb and it appears it has some sediment(?) in it. I swapped it out for one of the other bulbs that I have and this seemed to help, but it still has a small wedge shaped amount of brownish tint to the beam. I noticed the others have a very small amount of this sediment in them too. I've had a BB in the past, but I don't know if my old BB bulb had this as well or if this is normal with these bulbs? I never looked that close at my old bulb as I had no need to. The beam on my old one was flawless though, so I suspect it may just be ?old bulbs? I don't know, but I plan to call Dan and see if he can help, but I was wondering if anyone else has encountered what I'm seeing in these bulbs. Any help would be much appreciated.

Thanks,
Dan

Everything you describe is 100% normal for the Fatboy. The "sediment" are the solidified "salts" that vaporize when the bulb is ignited and running.

Ok. Thanks for the input. Any idea why my beam looks like it does then?

If you're referring to the yellowish/brownish triangle slice of pie in the spot, that is normal.

If this is a P32d-3 bulb like the 81522 or the dl50, the wedge is from the return wire blocking some light, and the use of a standard reflector.

Yes, this is exactly what I'm refering to.

It looks like my bulbs say Philips DL50 8J15? I know that they were bought new during the original run and have never been used. Is there an upgrade to the original stock reflector?

All I meant by commenting on standard reflector meaning round reflector. Some devices use "free-form" reflectors that are actually painstakingly engineerred to produce a very specific pattern. One of my interests is automotive lighting, and the OEMs use very fancy optics.

Dan, all of my BB bulbs have the yellowish reside on the south side. Must be normal.

Thanks Stephen for checking. I think my recollection of the beam pattern was off. I need to her outside and just enjoy her which I haven't done yet.
