Can't be truly drop in as let's are DC powered. Single point led in the 300w range will probably need a 72v DC power supply. Still if it shoots quick, geat potential here.
Lets also not lose sight of the reason things expose so fast is because of how close the LEDs are... So going single point does give you a long lasting cooler bulb but probably won't reduce exposure times like the multi led systems will.
