Switching to LED from CFL?

Hi,
I'm about 4 weeks into flower under CFL for soil-grown white widow auto, purple grizzly kush, and truth band. All 3 girls are looking really good.
I'd like to boost yield for the rest of the grow, thinking about switching from cfl to 300 w led panel.
Would this stress my plants, do you think?
Thanks!

You're better off just getting an HPS lamp. Only a select few LED panels will actually do better than HPS, and they cost a shit ton of money. If the option is between cheap leds and HPS, definitely go with HPS. LED is almost always a mistake unless you're looking for an expensive hobby.

I hear a lot of debate on this subject and I have done a bit of research but I am attempting to do my first indoor grow this year and am interested in trying l.e.d light as well. I also was looking at 300w l.e.d watt setup in a 5x6 foot walk in closet but only plan on using enough space for one plant. So with 3x3 max setup would a 300w l.e.d setup be efficient enough for even 1 plant ?

It sounds like you should really be using HPS. You didn't specify what type of leds or how they'd be driven, so I assume the worst. (probably 7-15% efficiency)

Even if you did your homework and learned everything you needed to know about making a DIY cxb panel, it would still probably be better for a noob to use HPS for a first grow.

Thanks.
My cabinet is 5 x4, runs about 87 degrees with two 4" passive intakes and a 120 CFM outtake.
I think HPS would cook my plants in such a confined space., especially when 400w of very well vented cfl runs on the hot side.
I am not going to do a DIY led, bought an Apollo Horticulture 300W led panel.
What I'm really trying to get at is, will switching the type of light (from cfl to led) during flowering stress the plants?

At 87f , even the LED's will cook the plants! You have to get that taken care of regardless. If you have tall plant/s then i would surely use a DIY cob setup or a hortilux HPS system. Since you are already in flower you will need to buy something already built and definetly drop them flower temps. 87F is really fucking hot for cfl's and it leads me to believe you are pulling 80f air from the intake

Are you in hydro or soil,

Yeah my bad I got busy and forget to do that
This is what I'd be using well 4 of the 80w if I decide to go this route
I was looking at a 300w single unit panel but lumen output was shit.... A few of these would be better than the 300w one I was looking at earlier. I don't know I'm still searching for different l.e.d lights and comparing lumens to watts to price
Another reason I want to go the approach of fairly low watt l.e.d setup is because I need a fairly cheap setup(tight on cash) and it needs to be low key. I can't be cutting /making holes in my wall/house inside or outside for proper ventilation/cooling and all that other stuff I believe you need to do for those hps and those other type big lights. If I can just use an a.c or something that's fine but I need more info on that...
I basically not trying to get the best optimum amount of light and best/big bud I can get.... Stupid I know. But I'm growing most my crop outdoor mind you. This is jus a mini project and I just want the minimum amount of light to do a cheap under radar efficient grow for one plant to salvage atleast few ounces. So that being said would something like this be efficient enough ?
Or like I said if I could get more info on a lowest watt hps light setup with some cooling tips to keep heat down And air circulated that be sweet too. Thanks

you will be greatly dissapointed in those screw in socket led bulbs, the lumen output is measured directly in front of the light, but you can put your plants that close to the light, and the lumens fall of fast with those, if you want small low watt draw, but bright , high lumen, h igh par output, just put together a couple of cree cxa3070 cobs, here look at this guys grow under just 2 of these cree led cobs, he is pulling only 104 watts total and harvested 105 grams dried, in a very small space, this will be your best option than anything screw in socket or cheapy chineese

Word thanks for the time/info
