http://www.1999.co.jp/eng/10161105 so i bought 3 sets of this and figured i would share my finidings.
To begin with i installed 2 sets into my kato ginza lines and did some short testing. (darn fine model by the way)
I compared with my kiha 110 with the old lighting set and ran 1 motor car of each together on the same line to be fair.
Before testing i cleaned the track with my newly acquired tomix cleaning cars and cleaned the wheels on the 110.
The old lighting set has always had a flicker problem.
Comparing the 2 together i can notice a vast improvement of the new lighting system to the old one. The new one has almost no flickering at all on DC.
To test things out fairly I installed the new lighting system in the kiha 110 car and ran again there is a noticeable difference between the old and new kit. I also would like to note it did flicker still more than the ginza did however it would only flicker once or twice per loop which is a vast improvement still.
On a side note I thought I'd mention here about using this new kit in older models. While I have found the kit works in some older models it's not necessarily going to work in all.
It is a bit thinner than the old plastic strip which means it will not hold to the roof as easy.
Although this should not be much of an issue if you use some blue tack to give extra hold.
It seems like a waste of time using in a shinkansen such as the e5 as the strip seems to be a notch or 2 shorted than the old kit meaning the e5 will not get lighting at the opposite end very well.
In addition to this the stip cannot hold at all in some of the carriages and would require an alternative such as blue tack to hold it to the roof.
I hope you find this informtation useful.
Cheers,
Dave
