Will changing bulb from 55W to 35W increase arc intensity?

[2100]

Just wondering if the 35W HID bulbs has a shorter arc gap which will bring about a brighter arc intensity and shorter arc. As you know the 55W auto ballasts are really in the 45W range to the bulb.

Just got some a pair of 55W (seller willing to mix 4300K and 3000K). If so I will get some 35W to play as well.

55W & 35W bulb has similar arc gap, you might need to look at the bulb to decide if the gap is any different.
I looked at the 55W vs 35W & it was hard to tell if the arc gaps are different.

I suspect 35W Philips bulb might have a shorter gap, as I got 40% more lux when switched to a Philips bulb,
but I didn't investigate the gap when I had the Philips lamp on hand, so this is just a guess thinking back.

the 75W bulbs have had a noticibly longer arc gap.

I see, then I guess no reason to play around with the cheap 35W on aliexpress then. Thanks!

Wow....check out the gaps of my 55W SM5200 and 35W Amondotech 3152 35W. The Amondotech 35W has a 5mm gap while the SM5200 55W has a 4mm gap.
