hmmmmm
So let's see how it should run. Correct me please if my math is wrong as it's late.
+ 1.50 single AAA voltage
* 3.00 Quantity of batteries
----------------
+ 4.50 Total Voltage (assuming series configuration)
+ 1,000.00 mAh (can range around "900 to 1100" mAh per AAA cell).
* 3.00 Quantity
----------------
+ 3,000.00 Total mAh (assuming series)
+ 4.70 Watts (as advertised)
/ 4.50 Volts from above
----------------
+ 1.044444444444444 Amp draw while on
+ 3,000.00 Total mAh
/ 1,044.00 Amp draw in mA
----------------
+ 2.873563218390805 Hours theoretical run time.
From what I have read, the current (or old now) Intova 4.7 W torches have a 5 V cutoff. That said, even with the batteries in series, they wouldn't power the LED driver.
SomeAssembly,
Please put some batteries in it and see how long it actually burns. If you do get near 3 hours, that would be a fantastic torch. I only get a couple nights out of my CR123's as it is (Perhaps three nights) that is assuming 2.5hrs over three dives.
The price is certainly right at 37.95 at B&H:

Do you have an older Intova 4.7W 120 Lumen torch that you can show us a side-by side with?
EDIT: Sorry. You said you have the 4.7 wide. If you take a picture alongside the wide, I can post images of my Nova 4.7 against my Nova wide 4.7. Not the best way to do a comparison but better than nothing I suppose.
To that end, anyone from Intova want to send me a sample that I can play with? If this stacks up to the other 120 Lumen torch, I'll be buying a couple.
