Compliance & Safety Standards

The HALO Phoenix eclipse lens meets ISO 12312-2:2015, the international safety standard for filters intended for direct observation of the Sun. The product is and listed on the American Astronomical Society's reputable Suppliers of Safe Solar Viewers & Filters list. Independent testing was performed by ORLAB at UNSW Sydney, one of the few internationally accredited labs for solar-filter testing.

We're careful with our language: ISO 12312-2 is a standard, not a certification. "" is a manufacturer declaration of conformity, not a third-party approval. The AAS publishes a listing of suppliers with credible evidence of conformance, not a government certification. We try to match our claims to those facts everywhere on the Site.

The standard specifies optical, mechanical, and labeling requirements for solar filters. Our eclipse lens blocks 99.96% of visible light and the IR/UV ranges required by the standard.

The eclipse lens was tested by the Optical Radiation Laboratory (ORLAB) at the University of New South Wales, Sydney. ORLAB is a NATA-accredited laboratory that tests sunglasses and solar filters to ISO 12311 and ISO 12312-2.

The Phoenix bears the CE mark as personal protective equipment for direct solar observation under EU Regulation 2016/425. The Declaration of Conformity is available on request to hello@haloeclipse.com.

Inspect the eclipse lens before each use. Do not use if scratched, punctured, torn, or separated from its frame. Supervise children at all times. Polarized and blue-light lenses included with the Phoenix are not safe for direct solar viewing, only the magnetic eclipse lens marked ISO 12312-2 is. Do not view the Sun through cameras, telescopes, binoculars, or other optical devices while wearing eclipse glasses; that concentrates solar radiation and can cause permanent eye damage.

If you believe a Phoenix lens is defective or has a safety issue, stop using it immediately and contact hello@haloeclipse.com with your order number and a photo. We will replace the product and investigate.
