I have a PowerTac Chameleon (very fun light if you like color LED).
------------------
PowerTac Chameleon
multiple Cree XP-E (numbers/spec from the powertac site):
- Red: Cree XP-E 625nm, High/Strobe 110 lumens, Low 40 lumens
- Green: Cree XP-E 530 nm, High/Strobe 150 lumens, Low 50 lumens
- Blue: Cree XP-E Royal Blue led 460 nm, flux on High 765 mW, flux on low 260 mW
- UV: 4x led, 380 nm @ 15 mW
- Mixed Red/Green/Blue: White-ish Light, 30/60/120 lumens, also Strobe
- Mixed Red/Blue: "Magenta-ish"*, 80 lumens
- Mixed Red/Green: "yellow-ish"* 135 lumens
- Mixed Green/Blue: "Cyan-ish"*, 120 lumens
*my perception
Misc:
- Magnetic ring switches between light combinations
- Battery: 2 x CR123A or 1 x 18650 **
- Dimensions: ◦ Length: 144mm
- Bezel Diameter: 58mm
- Body Diameter: 25.4mm
- Tail Cap Diameter: 34mm
- Weight: 253g (Without Batteries)
** For me, keeppower 18650 doesn't fit (due to diameter), but Eagletac 18650 does.
------------------
Comparing these two Chameleon's (basing on specs in AN/MPQ-53's post)...
- The powertac is better for color combinations.
- The nitecore has a dedicated white - with the powertac one can only get a white-ish effect with RGB.
- The nitecore has more powerful color led, not sure about the rgb leds.
- The nitecore looks like it will be an easier carry (smaller bezel/head diameter).
I'm pretty excited by this. I see myself getting a CR6 (White/Red) to serve as a backup light for my long bicycle night rides - white to backup front light, red to back up my rear light). If price is reasonable I will probably get the others too for fun.
