“New” Q Light #6530 vs. “Old” Q Light #6503

[Chris in MN USA]

Hello, all-

I have a question regarding the Weber Q Lights, specifically comparing the “New” Q Light #6530 vs. “Old” Q Light #6503.

Older version appears to have three LEDs, vs. the newer version, which appears to have only one(?) LED.

Old one mounts w/sheet metal stamping between handle and spacer, new one has plastic clamp that goes onto handle.

1) Can anyone tell me if there is a noticeable difference in brightness between the two?
2) Can anyone tell me if the older style will fit the handle on a Q2200?
(I have a line on an older model, locally.)

Thanks!
