Do you need help identifying a 🌶?
Is your plant suffering from an unknown issue? 🤧
Then ask in Identification and Diagnosis.
lighting what color LED lights should I get to induce flowering?

I have zero experience with LEDS. Actually about to scream for help figuring out what to purchase. But I do have experience with Metal Halide and Hight Pressure Sodium which might help since what we are talking about is spectrum. Old school cannibals growers use Metal Halide for growth and High Pressure Sodium for flowering, but the day cycle is what does the actual triggering. I think it is 12 hour nights and the stuff flowers.
Peppers seem to grow best with a mixture of the two lights and dont much care about day length. I think it is because they evolved closer to the equator where day / night cycles are not so different.
My guess is go for full spectrum, but I understand you can save on electric by eliminating unused portions of the spectrum.

Think this article might shed some light on the topic:

If you are using white leds to grow and flower you want between 3000-3500k color temperature. The spectra of this color temp is red enough to not limit flowering.
I've used roleadro 300w warm white on peppers with good results but I will be upgrading to cobs for all my indoor plants. The roleadro lights are not the latest tech but they are cheap and have a higher quality spectrum. I also have fruit and flower on a ghost pepper with a much whiter (more blue) led spectrum. I hate looking at the "blurple" grow lights not to mention the cutting edge is far ahead. Additionally some of the flowering may simply be based on genetics and not light at all assuming a quality spectrum.
Looking for good lights?
Check out the wire frame kits from timbergrowlights.com a 300-400w 4X4 cob array should give you great results in a 3X3 - 4'X4' area. Obviously you can go crazy with the lights and production by buying bigger arrays and co2.
Chilledgrowlights.com are the absolute top of the line with a proprietary spectrum that includes uv deep red and some ir.
Do not judge leds based on watts judge them by the photons produced. An inefficient led chip may consume a lot of power at the wall but produce poor quality light or even worse create a lot of heat. It's all about efficiency and many led arrays are not efficient. This means for every watt you consume you should yield more light than heat compared to other light sources. Running LEDs at max current often is not the most efficient means to run them. Many of the cob arrays run the leds at half their max watts (50-60 watts instead of 100) to reach peak efficiency which is the ratio of heat produced:to photons.
