These are three different models of the Quark line. You pick whether you want a floody, throwy or in between light, and then Lego it for your battery preference. In general, the smaller the emitter and larger/deeper the head, the more throw the light will have. (note, none of these be a pure flood like your ZL502)
Most throw: Quark Turbo AA2 (QB2A) - large/deep head, small R5 emitter. Only comes in 2xAA so you need an optional 1xAA body.
Medium throw/flood: Quark Pro AA (QPA) - small head, small R5 emitter. This comes in 1xAA.
Most flood: Quark AA2 X (QP2A-X) - small head, large XML emitter. This only comes in 2xAA so you need an optional 1xAA body.
On 1xAA Alkaline, NiMH, or Lithium primary, they'll all put out around 100-115 lumens - However, I have a ZL H51w which states 172 lumens, but it looks the same as these Quarks to me (ceiling bounce test).
