ITP

iTP Light Electronic Co. was a Chinese company founded in 2007. It was owned by Olight. In August 2011 the A series lights were modified and merged into the Olight line (as the i series) and any remaining iTP lights were discontinued.

A Series
A1 EOS - 1xCR123A 3-mode twisty with a Cree XP-E Q5. Output is 1.8, 35, or 190 lumens. Introduced in November 2009.

A2 EOS - 1xAA 3-mode twisty with a Cree XP-E Q5. Output is 1.5, 18, or 80 lumens. Introduced in November 2009

A3 EOS - 1xAAA 1 or 3-mode twisty with Cree XP-G R5 LED (introduced in January 2011). Available in a 1-mode standard edition or the upgraded 3-mode version with 1.8, 22, and 96 lumens. Upgraded version is slightly longer than the standard. 10440 li-ion batteries are not recommended because the light gets hot quickly, but is very bright in short bursts. The standard edition is available only in black. Upgraded versions have more color choices: black, blue, red, purple, and gold as well as titanium and stainless steel. This light is very similar to the Maratec AAA. Introduced in July 2009, the 1st Generation had a XP-E Q5 LED and modes of 18, 1.5, and 80 lumens (modes were Medium, Low, High). It was available in many colors including a natural gray that was dropped in later editions. In August 2010 2nd Generation 3-mode versions began shipping with modes ordered Low, Medium, and High with a higher rate of PWM, tighter threads, and a lobster claw keychain (instead of the original squeeze ring). The 2G version seems to be available only in black. In November 2010, a limited edition titanium A3 with a Cree XP-G S2 emitter was released in a kit with an iTP R01 and solar charger.

A4 EOS - 2xCR123A 3-mode twisty with XP-E Q5. Output is 3, 30, or 160 lumens. Introduced in May 2010.

A6 Polestar - 6xAA 4-mode Cree MC-E LED with reverse clicky switch on side. Output levels are 12, 160, and 700 lumens. Batteries are loaded into a carrier and then this slides into the body. Reviews: Selfbuilt
