Observations of three planetary nebulae (PNe) with (N II) wavelength 6583 is greater than H alpha are presented. They are He 2-111, He 2-145, and He 2-152. He 2-111 has already been classified by several authors as a type I PN. It is concluded that He 2-145 and He 2-152 are both type I PNe. Physical parameters of the nebulae and the central stars are given. It is found that He 2-152 has an extremely high He contents. The luminosities of the central stars run from 340 solar luminosity for He 2-152 to 1090 solar luminosity for He 2-111. When using distance-independent parameters for the determination of the luminosity, much higher values are obtained, running from 5200 solar luminosity for He 2-145 to 19,800 solar luminosity for He 2-111.
