Peak Pacific With Alkalines Or Sanyo Eneloops. Which Will Be Brighter??.

I have a peak pacific that I had upgraded to about 570 candlepower. I am using regular AAA energizer alkalines in it now, but I have some AAA sanyo eneloops coming in a few days. Does anyone know if the eneloops will give the pacific the same brightness at the beginning like the alkalines?. Or will they make it a little dimmer?.
Thanks in advance...

It should be slightly dimmer at the begining, but you might not even notice. The alkaline will dim to the same level as the NiMH pretty quickly and the rechargeables will be brighter from there on. The eneloops should give you a longer runtime.

570 candlepower sounds like the super power version, which will kill an AAA alkaline almost immediately. You definitely want nimh or lithium. You may be better off getting the AA battery tube and using an L91 AA lithium.
FWIW, I just measured about 210 mA current draw from the used AA Ti Pacific HP that I just got here on CPFMP (HP is about half as powerful as your light). At 1.7 volts that's about 357 mW though there might be a little sag. With a NiMH cell the light is NOTICABLY dimmer and I measure the current draw at 140-150 mA. At 1.2 volts and 145 mA that's 174 mW, just about half the power of the L91 and the converter is likely to be more efficient at the higher voltage too.

So, I think that the Pacific circuit is really not all that happy with NiMH or alkaline, though the HP AA version can subsist on either. It really wants lithium. Sigh.
