Light heads (since LEDs) are solid state electronics and it's completely a non-issue. Any overheating concerns would happen in around the first 15 minutes of the light being on, 1.5 hours vs 3 hours isn't going to make a difference. If it's a brand name light it's designed to work that way, specifically designed to be able to swap battery packs in overnight races and keep on going.
