How to supplement 730nm without a new led light or IR puck?

[LeeWD]

My 500w light doesn't have any 730nm leds, and I want to provide that for "sleepy time" at the end of the daily light cycle. HLG used to sell the Flowering Initiator Far Red Bulb Specifications. 15 Watts, but it appears that is no longer sold by them. Is there a good alternative to give a 4x4 enough 730nm for an easier sleep cycle and quicker flowering bud set? Ty in advance
