Do you already have the HPS?
If not get CMH's with Phillip's bulbs
No I haven't. CMH are better? I will looking that

all you have to do when changing light sources is acclimate the plant to that light
for example run 25% power 25% distance , next day 50% power 25% distance, then 50%/50%... slowly work towards max
you should do this when changing to any light source. The sun, HID (hps/mh) or LED.
I think flouro's need the least acclimation as they aren't an agressive light

Yes, considerably IMO. I replaced a 400WMH & 2x600WHPS (2 cool tubes) setup with 3x315CMH (no cool tubes) and even with the ballasts inside the tent it's no warmer. Bulbs last longer too.

I'm a LED guy from seed to finish..the pic of the canopy is at day 47 vegetative stage.. but yes you can go from one to the next if you know your light distances..

What is the way to judge these lights?
I like the LED too. My issue is cost of LED.

I never had a problem with cost when at $70-$240 for a light isn't bad been using same lights for over a year now... $70 light is 300watt full spectrum and the $200-240 is a 900 watt full spectrum.. currently I use 2 300 watt for flower... 1 300 watt for vegetative stage.. in a 3x3 tent both stages same size tents
I was basing off lights like Kind. I ain't to knowledgable about that stuff and would have to buy the light ready to use

With most LED lights those wattage numbers are wildly inaccurate.

Light ready to use of Amazon is viparspectrum comes in many lights but just do a search for led grow lights and choose a "viparspectrum" for brand...... distance from top of canopy during veg is 24-34 inches depending on age.. just watch your upward growth to fast is the light is too far away no more than 1/4 inch a day.. during flower for first two weeks I'd keep 2 300 watt led at 28-30 inches from top of canopy... only have to raise lights when canopy has grown 2-4 inchs closer(both stages) after the first two weeks of flower you can stop raising lights but not to let the canopy or top of buds get any closer than 18-20 inches...

Not in the sense I'm sure your trying to make... L.E.D.s use less wattage for draw of power.. L.E.D.s only use less power to create light.. with true full spectrum L.E.D. lights you get an even greater bandwidth of light spectrum as well..
Not that I don't care about cost but..... I am more for the best light possible

Exactly in the sense he is trying to suggest. You have a 300w light and a 900w light, neither of them draw the power stated in the title.
Misleading!
Why not call them what they are 130w light? Because that wouldn't sound as good.
300w light is a stretch of the truth unless it draws 300w.
Smoke and mirrors.

Babies and teens are perfect for T5's/T8s. I agree with you.

You obviously dont understand power from light.. your light say 300 watt hps/ms only produces 300 watts of light while consuming 300 watts electricity while my say 300 watt full spectrum led produces 300 watts of light while only consuming 130 watts +/- 3%.. just because led use less electricity to produce light doesn't make it smoke and mirrors lmao...
