It might be lower rated lumens, but it may have a different beam profile (tighter hotspot, or less light wasted as spill) which makes it seem brighter
An example, - I have a Maxabeam (1500ish lumens) and a Ryobi Hid spotlight (3200ish lumens - almost twice as much light coming out)
With them aimed at the roof, in a small room you would say the ryobi is brighter, which it is
if I then aimed both kits across an oval, or across a canyon, the Maxabeam will thow a tiny hotspot a long long way, under those conditions it looks "brighter" to most people.
The tint shouldn't change the perception of brightness too much
