I am sure there are some better ideas out there for features so lets hear them. This is what I wish a strobe manufacturer would come out with:
Power: Guide number UW of 30-40 - Good power to weight/size ratio
Color Temp: Daylight/5500k - With digital and RAW I think 5500K is a good starting point.
Power settings: full - 1/64th in 6 steps - More settings I think is unecessary.
Battery: AA user replaceable 2500mah NiMh - NO special NiCad batteries. I want to be able to replace my own batteries and fall back to AA akaline in an emergency.
Double o-ring seals on cords - Seems easy to do but few manufactures have this.
Manual control - NO TTL, really manual is simple and with dual strobes you can get more creative shooting manual. Besides, it seems to be nearly imposible for the strobe manufacturers to try and reverse engineer the TTL system that the Camera makers keep coming out with. Save the R and D money and lower the cost of an all manual strobe.
Built in modeling light - No laser beams, I just need enough light to help judge where the strobe is pointed and to aid in focusing.
Built in Slave sensor - Nice if I want a diver to hand hold a strobe for me or if I break a cord, I can still shoot with two strobes and one cord.
On/Off switch with 3 settings - On-No Model light, On-Modeling light ON, ON-Slave
Compact housing with a double sealed battery compartment. The only flood problems I have had have been with a strobes bad battery compartment cover design. I like the clear Inon screw cap battery compartment cover, you can see the O-ring and tell if it is seated propery at all times, plus the o-ring is hi vis yellow.
