I2C and Logic Level shift, or different FETs?

[Magimedia]

I've got one of the 16 channel PWM modules that I intend to control RGB strips with. I'm not sure on the current draw per strip, but I think it's around 600mA per channel.

I have some IRL520N MOSFET that I have used before to control the strips... but that was on a 5V system, and the Pi I2C is 3.3V

This leaves me with a dilemma... would it be better to use a logic-level shift and move the I2C up to 5V, or should I replace the FETs with something that has a lower Vgs? The logic level shift seems to be the cheaper option, but do they work with I2C ok? I know they say they do on the eBay listings, but that's always to be taken with a pinch of salt...

If you use the level shifters Philips invented for I2C then they will work fine

FWIW, I've tried the level-shifting modules linked-to below - some of which are (marketed as) I2C safe. There are further links to circuit schematics etc. for the uses I've put them to within that webpage.

Thanks - I got a generic level shifter (looks like your D, but came from eBay) - seems to be working ok with I2C as I can use the clock module ok as a test.
