What's a good light meter for measuring projector brightness?

Thanks,

Would the CA811 work as well for projector measurements? It's quite a bit cheaper and it looks like the only difference is top-end range on the CA813 is higher. Also, I was looking for a ftL measurement. Is there a conversion from lux (or ft-candles) to ftL?

Thanks,
Darrell

ftL = (Lux/10.76)*screen gain
