Makes it much easier to drive them and while they still need a decent heatsink, you might be able to get away with one fan for multiple units of these LEDs. The 100s need some weird voltage like 36 VDC to drive them and power supplies/drivers in that range are less common. Plus, with the 10 watters, your colour mixture can be better customized. Price is better as well & if one 10 watter burns out, it's not as much of a kick in the a$$ to replace. Make a mistake with the 100 & burn it out, it's a few $$s more.
