We have a Red Chili D 2024 on our sportsman, and after the first shirts start going under the flash, for a typical Gildan Ultra shirt, the flash time ends up around 4-4.5 seconds (with the temperature sensor set at 200 degrees F) the bulbs are 2.25" above the platen when the table is up.
Ink is quick white, non modified... platens cold. once the platens warm up, the flash time gets even lower...
-- this is one reason I really like the 'D' model of this flash, you can watch the bulbs and decrease the flash time on the press's control panel as you go to index even faster.
