If I wanted to buy more whitestrips but already have the light - which strips are compatible?

There is a "Professional Effects" with a Light kit. So I would think the Professional Effects would be compatible...

When should I use light? End of 60 min? Or right after applying whitestrips?

We recommend applying the light after 60 minutes.

My kids used 3 of my strips, not realizing they were part of my light kit. Can I just use any crest strip as a replacement?

Hi, Teej. The Crest light device is designed to operate with the Crest Whitestrips that they are packaged with. They are not sold separately; and are not meant to be used with non-light Whitening Kits. If you have any other questions for us, we're here to help. Just give us a call at (800) 395-8423. -The Crest Team

Can you use the crest 3d white whitestrips with the crest 3d white brilliance 2 step kit?

I’ve used the stripes and light after brushing my teeth with the 2 step crest kit. There is some extra sensitivity, but to each their own. I was doing it to further strengthen the outcome of whiter teeth. I’m Happy with the results.
