Mars tsw2000 or T8 reptisun for seedlings?

Morning
I have germinated my seedlings, they have sprouted tap roots and ready to go into some peat pucks and into the propaganda dome. I have the mars hydro tsw2000, 300 watt dimmable light.. I also have a 15" T8 reptisun tube light I was using for my bearded dragon. The dome has a lid which would allow my to get the t8 10" away. Which light would be better?

I started mine out with the TSW2000 and when they got big enough, dropped them under the TSW3000 (with the TSW2000 supplementing)

I'm trying the mainlining technique so I vegged my plants for 10 weeks to train them and develop some thick pipes to send nutrients to the buds. I just started week 4 and they seem to be doing well.

This is my first grow with LEDs and I'm sold. I liked my MH lights, but they put out so much heat and spun the power meter like a top.

My two cents is to just go with the TSW2000. It's a good light and if you find any signs of light stress, you can just dim them down.

Did you go with full power right out of the gate? How far away did you have your light for those first days and couple weeks? Did you use a seedling dome?

You just need to be careful and conservative when you first start seedlings under a strong LED. Don't start at full power and give them plenty of distance, then if the seedlings stretch, lower the light little by little. Fluoros are great for starting seedlings but I wouldn't go with a single bulb reptisun over a decent LED. A multi-bulb fluorescent fixture is my favorite way to germinate seeds and start seedlings for the first 2 weeks-you end up with nice strong, compact seedlings. If your seedlings stretch under LEDs, you can always bury them deeper when you first repot them, to deal with the extra long stem.
