I think if you try the "narrow" MFL / FFR bulbs instead of the very narrow ones you will fall in love with these PAR lights. I think that the slight frost those bulbs have on the front glass make them much easier to use as the beam is more spread out than the VNSP with only a small loss of light. I also often put a layer of Opal over these and that will give you a fairly even yet very direct light.
I think these are the great lights for the money. I have 6 of the cans and also a 9 light Brute that I have used for years. I often use these instead of putting CTO on HMI's or when I need a warm light. And they are great to use with dimmers.
I have the wide bulbs but find I rarely use them as there are many other lights for that, my fav is the narrow spot: 1000W PAR64 120V (FFP)
Lights64 on eBay is great for all bulbs, good guys and usually the best price - these are less than $18.00 + S/H.
