More LED Madness - Rear Lamp LEDs, Part 3

OK OK so my OCD got to me...despite the Phillips LEDs being significantly brighter as well as instantaneous in lighting up, their design - with those wide fins - results in dark vertical shadows that of course bother me.

So, it was back to searching Rakuten for alternatives.  Unfortunately,  I could not find another well known brand name manufacturer that sold an LED of the right size and spec, and equal or greater brightness.  I did, however, find an online store called "Pika-Q" that specializes in automotive LEDs.

Despite the silly name, not only did they have an S25/1157 (P21/5W) product claiming 200 lumens of brightness, they offer an 18 month warranty as well.
Just in case someone at Nissan asks me for LED advice, I got these which fit the NV200 Nissan van.
As the design shows, not only are these fin-less, but also shoot a red beam directly backwards through a lens, using Chip on Board (COB) format, with the underlying circuit board white colored (thus Pika-Q calls them "White COB").


Here are the specs:
200 lumens when braking, 30 lumens tail light. Power consumption of 6.0W and 0.8W respectively. 
So I went ahead and ordered one pair to test out. My thinking was, while there might be other LED bulbs that claim to be even brighter, I would be happy if these worked out by being just as bright as the Phillips, so long as the dark spots were gone.

A few days later, they sent me a pair of these LEDs in a nice flat box with some other goodies (free black rubber work gloves... I'll post a photo later) and so I went out and immediately fitted them.

Immediately, I could see that the dreaded black vertical lines were gone (left lamp below):
Philips bulb on the right... and does it look slightly more orange?
And taking a close look, the colors seemed a bit different.  In order to confirm this, I took this next photo:
Pika-Q is definitely redder, whilst the Philips has a bit of an orangish tinge
I took some video too. This first one, I wanted to make sure both the Philips and the Pika-Q lit up at the same time.  Unfortunately it's not very well focused, but check out the two Philips LED bulbs on the left, and the Pika-Q LED bulbs on the right...

Actually, the fuzziness helps make the vertical lines on the left side stand out more...

This one is better:

And further, maybe you can tell the color is different?

Here are two photos to show the differences:

Philips:

Pika-Q.

Anyway, based on this result, I went ahead and ordered another pair of these red LEDs from Pika-Q, to complete the other side.  But, I took advantage of this timing and ordered a couple of extra items, which I will feature in my next post.

Need to see the difference between the OEM bulbs to the Pika-Q White COB, if you have the time for it.
