Hello,
I've been using square 56x52mm 100w led chips with separate 110 VAC driver power supply with good results. I've noticed a lot of people are using the larger rectangular 160x45mm 100w chips with on-chip power supply. These run directly on 110 VAC.
Was wonder what everyone thought of them? I'm assuming they will need substantially larger heat sink/fans? Thanks
