What the differences mean
At the 7-iron, the Hot Launch HL3 is 32° and the Hot Launch HL4 is 31°, a 1° gap. Each degree of loft is worth roughly 3 to 4 yards of carry at the same swing speed, so the Hot Launch HL4 should carry roughly 3 to 4 yards further with that club, on a slightly lower, shallower flight than the Hot Launch HL3. Across the 10 clubs both sets share, the Hot Launch HL4 averages 0.8° stronger, with the largest gap at the PW (46° vs 44°). The pitching wedges are 46° and 44°; the stronger one leaves a 6° jump to a 50° gap wedge, which matters when planning wedge gapping.
The sets are built differently: the Hot Launch HL3 runs 3-iron to LW (11 clubs), the Hot Launch HL4 4-iron to LW (10 clubs).
Both are game improvement irons, built for roughly 10 to 25 handicaps. Perimeter-weighted cavity backs with wider soles, more offset and stronger lofts, aimed at mid handicaps. Because they target the same golfer, the decision comes down to the specific loft, feel and shaping differences rather than who the sets are made for.
The Hot Launch HL3 is listed as cast cavity back with an expanded undercut cavity, variable face thickness and a notch hosel (3-7 irons) that shifts weight to the toe and the Hot Launch HL4 as cast cavity back with an expanded undercut cavity and toe weighting. With the build method this similar, differences in feel come down to head size, sole width, topline and offset rather than how the heads are made.
The Hot Launch HL4 arrived 1 year after the Hot Launch HL3, a typical one-generation refresh. Changes over that span are usually incremental: refined face thickness, revised weighting, updated looks and small loft tweaks rather than a new concept. Here the 7-iron loft moved from 32° to 31°.
Which should you choose?
The Hot Launch HL4 is the stronger-lofted set — up to 2° stronger than the Hot Launch HL3 on matching clubs. Expect longer carry per numbered iron but a flatter descent angle; gapping at the wedge end is where that shows up.

Frequently asked questions
Is the Tour Edge Hot Launch HL3 stronger lofted than the Hot Launch HL4?
No. The Hot Launch HL4 is the stronger-lofted set: its 7-iron is 31° against 32° for the Tour Edge Hot Launch HL3, 1° stronger and worth roughly 3 to 4 yards of extra carry.
What is the loft difference between the Tour Edge Hot Launch HL3 and Hot Launch HL4?
At the 7-iron the difference is 1° (32° vs 31°). The largest gap on a shared club is 2° at the PW, and 7 of the 10 shared clubs differ.
Are the Tour Edge Hot Launch HL3 and Hot Launch HL4 aimed at the same golfer?
Yes. Both are game improvement irons, built for roughly 10 to 25 handicaps. Choose on feel, looks and gapping, ideally after hitting both.
Do the Tour Edge Hot Launch HL3 and Hot Launch HL4 have the same lie and length?
At the 7-iron, yes: both are 62.5° lie and 37.25 inches long.
