I can only speak from my experience as i have only got some lights... but wow do they make a difference... somewhat spendy but with most electronics you get what you pay for... the simple fact of how adjustable the fc6500 series is makes it easy to regulate light distribution to target areas and no need to worry about the tent over heating because you get plenty of cord to keep the power supply out of the tent!!! Super light so anyone can hang them solo. Great lights highly recommend.... 4 or 5 years old going strong... always had a dimmer issue tho
