On my 2nd set of Silverstars in my '06.
I did the lumen meter check doing the upgrades, I am still trying to find my notes on it from my truck.
1st was the stock Sylvania bulbs to Sylvania XV bulbs ( H13 Silverstars were not out yet ). The stock bulbs were less than 1 month old. Got a bump in the lumen output doing this ( seem to recall ~ 15% more lumen output ) and the color was whiter ( always do 1 bulb at a time when doing the testing ).
When the Silverstar bulbs were released, I installed them as soon as I got the new bulbs. The lumen meter showed an increase ( think it was slightly higher bump, but this was with old XV bulbs ) and the color was whiter yet.
Hard to say how new to new would be.
I had to replace them last year prior to the H13 SS Ultra release, so I cannot comment on them.
I did not like the H4 version of the Philips bulb when I looked at them for the motorcycle, so I never tried them in H13 format. I did the H4 Osram bulbs from Europe on both bikes, which is now what the Silverstar ultra bulbs are in the states. I do recall on the bike that factory H4 to Osram bulb, I had a 0.2 A power decrease when using a clamp meter on the factory wiring. I changed the wiring to use an external harness, and the lumen output increased again.
The lumen meter I have is not high end, so the spectrum is it limited ( I guess does not read above 5.5K or less ), so when a higher lumen output is registered, it is usable lumen.
The other thing that will help any bulb lumen output is using an external harness of larger gauge wire direct to a fused connection at the battery.
This is one point of gains to be had, and the least used when upgrading bulbs.
