I would not give much thought to the package ads. Their xtravision halogens and almost every bulb in their Silverstar lineup has that same "+30% more light, +20m" line. I wouldn't be shocked if this isn't more of the same marketing bs.
The spec sheet on these bulbs makes the usual Sylvania light output claim of; Up to 20 % more light. 20% more light than what is the question!
They list a light output of 3200 lumens, but at plus or minus 15%. (Same as the OEM bulbs)
That could mean they produce as little as ~2700 lumens or as much as ~3600 lumens??? What are are the true specs?
Ill try to grab some of the info off of hidplanet. Several members there have tested and measured the lumen ratings and have found that they do produce 3200+ lumens. I believe all were independantly tested and not subsidized by Osram.
Had a minute to grab some info. See this thread. First post has a bunch of reviews and one where the reviewer compared output of multiple bulbs and their lumen output.
"The numbers are off the wall in favor of the CBI's. I attach a string to the projector at a fixed distance and attach to other end to a remote sensor. I let the ballast and bulb warm up then I find the best reading by moving the sensor up down right left. It's in no way an exact measurment and is really measuring the hot spot.
I used a RX350BX for the test with a STI-R lens. I did this three times with each bulb in rotation and the number came up the same for each bulb (within 1 or 2 lm).
The closer to the lens you get the higher the numbers go so you can't compair these lumens to the number the OEM says on their data sheet. They just show the difference between these three bulbs.
66240 CBI 4143lm @ 173 degrees
66040 2740lm @ 174 degrees
85122 2554lm @ 169 degrees
I couldn't believe the CBI were so much higher but like I said above I did this three times in rotation, changing the bulbs and letting them warm up each time with almost the exact same results."
The review above is obviously an exceptional case but a 200+ page thread of people testing and comparing these bulbs to OEM and other high output HID bulbs, can't be completely wrong. Comparison pic after comparison pic showed improved color and brightness. The guys over there at HIDplanet are serious about their lights...I think they would call BS faster than anyone and that thread has been live for 3 years. Marketing is exactly what you say and as I mentioned I don't see the 20% improvement over say a 4300k oem bulb, but I could definitely see a 20% increase over a coated glass 5000k bulb, which as confirmed by xenondepot above, generally puts out 2800 lumens.
I'm not here to convince anyone to buy them. $180 for some HID bulbs is definitely not what I would consider inexpensive. If you just want a whiter color and don't mind sacrificing output, pick up some morimoto's or whatever it is that xenondepot sells. But the improvement in color and output has been absolutely everything I had expected and well worth it in my opinion, and I guess it is still supposed to get better as I have only about 5hrs on them. We'll see.
