Here is a short breakdown of the basic differences between he 3 lights:
- AL-528W – an all daylight color temp rated at 5500K and throws a 75 degree beam angle.
- AL-528S – an all daylight color temp rated at 5500K but throws only at a 25 degree beam angle (spotlight).
- AL-528C – has a 75 degree beam angle, but can adjust color between 3200K-5500K using two sets of different color LED bulbs.
Pricing for these lights starts at around $190 (keep in mind that they do come with just the wall charger and no batteries for off the grid usage). You can read the rest of the preview on cheesycam.
