Ok I would add a small basking bulb over one corner in addition to the led lights but be careful as too much heat can melt the styrophoam background. Monitor it with a good temperature probe. Also plan your build to allow for a lighting and temperature gradient. The leds don’t penetrate much below 18 inches so use low light plants at the bottom such as pothos and high light plants like neoregalia bromeliads at the top.
