Does the dimmer have a linear affect on the light's ppfd values? for example, its top value of 1006 at 100% is simply 754 at 75% and 503 at 50%?

I don't worry so much about par values your leaps on your plants will tell you everything you want to know. Don't make things too complex

What led is used? not smd... i know that it is a surface mounted device. what brand and model led is used? viparspectra please answer, not a customer.

Dear customer, P1000 used 3500k, 6500k, 660nm and IR 730nm diodes, and we are going to updated to Samsung LEDs in new version. The new version will be available on July or August. If there are any other questions, please feel free to contact us via Amazon message or email to support@viparspectra.com.

Will the p2500 get to hot in a 5 foot tall tent it’s a 2x4x5 foot tent would it light burn my plants?

this light definitely gets hot. I have it in a 2X4X5 tent and had to build a shroud over the driver that attaches directly to the exhaust fan. that completely solved the heat problem and was fairly easy to do.

So does the p1000 come with ir or not? product title says yes but reviews say no?

Dear customer, this P1000 light comes with 1pc IR diodes actually. Please feel free to order it.
