A follow-up to my previous question on MOSFETS.
Earlier I posted a question about wiring a MOSFET (https://www.reddit.com/r/ElectricalEngineering/comments/1pa6b1r/help_with_mosfet/) But I was told to get some more information so I did. The MOSFET is an IRLZ44N (https://www.alldatasheet.com/html-pdf/68872/IRF/IRLZ44N/46/1/IRLZ44N.html) and I am trying to use it to control a 30w LED COB (https://www.amazon.com/CHANZON-Power-Spectrum-Plant-Light/dp/B01DBZJCQS/ref=sr_1_2?sr=8-2). But when powered the LED is in an unpredictable state, sometimes off, sometimes on, sometimes cycling. (attached is a schematic and image of the part.)
EDIT: The PSU I am using is a 18-39v 900ma(constant), and I have the LEDs hooked up to cooling. The MOSFET is hooked up to 5v constant so I can manually test it before programming.
