Looking at both these lamps,im totally new to led growing and have just about zero info.....these 2 lights are in my price range and will cover a 4x4 area for flowering.anyone with experience using either or both lights would be appreciated.
Im in canada and if anyone has suggestions of another brand with similar wattage id like to hear about it...also any good sales online in canada.
Thank you

Im kind of leaning towards the vivosun for the simple fact that their customer service is supposed to be amazing.

That's a good light for that space.
Do your self a favour and get a light meter of some kind so you can measure the PPFD. You can use an iPhone and an app as well.
It will make sure you are using the light at optimal level.

Its 730 watts.i saw a youtube vid where a guy was using a l8ght meter with this lite in his 4x4 tent and he was super impressed with how even it was and how much light actually got to the corners of the tent

The lumens meter with the app has its limitations. It has a limited group of spectrums to choose from. Using as a lumens meter and then converting it here

The app I found for the bt338 did not have a spectrum choice close enough to my light and was reading 30% high. this conversion has a bunch of light spectrums to choose just find the one close to your panel.
