Updated Information on Sunumbra's CWL and UVAPF
by: Sue Ingram

The following is a summary of the updated COLIPA certification that was performed on all products last year:
Sunumbra Daily (SPF15) - CWL = 374.67; UVA PF = 7.18
Sunumbra SPF30 (Classic) - CWL = 376; UVA PF = 16.61
Sunumbra Sunkids (SPF40) - CWL = 374; UVA PF = 19.52
Sunumbra Sport (SPF40) - CWL = 378.53; UVA PF = 24.92
Sunumbra Family (SPF30) - CWL = 374; UVA PF = 17.18

The UVA PF details produced previously were not presented correctly, but rather represented the UVA ratio from the previous tests performed.

How do get 5 star protection?
by: Anonymous

Hi there sunumbra people :-)

Question: I thought a 5-star UVA protection meant you had a certain ratio of UVA to UVB according to the PF scale.

Just curious how can you get a 5-star rating for your product when, for instance, your SunKids has a UVA-PF of less than a third of the stated spf (and therefore it doesnt' pass COLIPA's guidelines let alone garnering a 5-star rating)?

Really interested to hear your thoughts. I

Sunumbra sunkids
by: Anonymous

Great numbers. Just curious why the Sunkids formula doesn't meet the EU requirements that the UvA protection be one third of the UVB. Great critical wavelength numbers though!!
