Proper prompts to disable lamps from my image

[Trylz]

I am adding stable-diffusion to my software. I want to disable some lights that the kernel added to my scene,
Here the source image:

Here the output of stable-diffusion :

As you can see it added two lamp light that i am struggling to disable.

The command line i am using:
sd-cli.exe --backend cpu --diffusion-model flux-2-klein-4b-Q8_0.gguf --llm Qwen3-4B-UD-Q4_K_XL.gguf --vae flux2.full_encoder_small_decoder.safetensors -p "turn the image into a high quality photograph." -n "Extra lights" -r BedroomSrc.png -o output_photo.png --cfg-scale 1 --steps 4 --offload-to-cpu --steps 4 --fa

Prompt i tried:
Prompt: "turn the image into a high quality photograph."
the negative prompt : "Extra lights"

Thanks for helping!

Negative prompts do noting if cfg-scale is set to 1.

Here's what I've got:

sd-cli.exe --diffusion-model flux-2-klein-4b-Q8_0.gguf --llm Qwen3-4B-UD-Q6_K.gguf --tae taef2.safetensors -p "turn the image into a high quality photograph, taken in daytime." -r BedroomSrc.png -o output_photo.png --cfg-scale 1 --steps 4 --offload-to-cpu --fa

sd-cli.exe --diffusion-model flux-2-klein-4b-Q8_0.gguf --llm Qwen3-4B-UD-Q6_K.gguf --tae taef2.safetensors -p "turn the image into a high quality photograph." -n "Extra lights" -r BedroomSrc.png -o output_photo.png --cfg-scale 2 --steps 4 --offload-to-cpu --fa

Your command :
sd-cli.exe --diffusion-model flux-2-klein-4b-Q8_0.gguf --llm Qwen3-4B-UD-Q6_K.gguf --tae taef2.safetensors s -p "turn the image into a high quality photograph." -n "Extra lights" -r BedroomSrc.png -o output_photo.png --cfg-scale 2 --steps 4 --offload-to-cpu --fa

Generate an error:

Yeah it's a copy-paste mistake, just remove the extra s
