Those are terrible greenhouse lights or even hobby lettuce light bro.
Surprised for Philips as they're a leading brand name for lighting & have made a few decent led grow lights.
Dude! Those lights are rated for only 25,000 hrs. Ummm, what, x2 or 3 bulb exchanges. So in a yr YOU'D NEED to buy a new one or buy new chips to replace those. Considering beafing the heat sinks too. Really??? After purchasing for TOP $$$. Fuck that noise.
Another example of the reduced longevity of poor thermal mngmt but initially decent #'s to get you to buy.
Many Fooletos are comparing fixtures outputs w/o taking into account the long term efficacy.
So sure, run your SBS's now against a proper led grow light design & come close to each other in harvested yields. Try that same shit in x2 yrs n let us know how you make out.
Depending on the company & design, many will be producing around 20%+ less yields then they did initially. In your old jobs case, using those Philips would be around a 40% light loss after x2 yrs. Damn.
Thats why we should all have Par-Meters IMO.
Just dump all your garbage & buy a proper single fixture. Its only a damn 2x4. No nred for more then one 300w Fixture.
I recommend the Amare Pro-3.
It will smash that 2x4 & produce much prettier buds then a plain white spectrum. They include the enhancements you need to be a shit ton better then Burple & a decent chunk better then plain white.
It is a 2x4 you're looking to fill with the Sun right? Getting threads confused.

Detachable 90• lens (easily screwed on & off by hand) 105• chrome reflectors, built in (not that white snap on crap) . MeanWell Driver for each Cob creating a fail safe unit. Vero Cobs for the past 2 yrs. Don't mind the old website. New one is in progress. Cree XpG3 Monos, separate mono + Cob switch. 35k cobs. Was the Equetorial Spectrum & is now the Canna-Spec spectrum. Daisy chainable, versitile, detachable case for easy access.
Clean conduit sleeves on all internal wiring, quite/quality fans, Copper-Core Heatsinks, laser-etched, gloss white, spiffy case made of Aluminum for weight reduction.
All their lights are Heavy-Duty & overbuilt in comparison to all others.
Amare has tuned their spectrum to be truly Horticultural. Grow lights HAVE TO HAVE IR or enough 630 + 660nm to compensate. They include all x3. Also white leds have a missing link around the 470nm range. Amare has that filled as well. One SE-Model has the UVB-T-8 included center fixture even.
Now, if i am on the wrong thread & you want the highest GPW w/o sacrificing bud size or quality then the Amare Bar-4 is what you want for a 2x4. Started the with the highest efficiency model available this yr. As well as the best spread/uniformity, thermal mngmt, components, highest DLI, so many options you can use incorporated into the Heavy-Duty fixture. Detachable rails, sliding rails, pivoting rails, x3 Rows of diodes per bar , not one. IP-66 Rated w/ real extra transparent, Gasgeted Glass protecting the goods. OverPowered @ 450w for the option to use bars as side-lights or cover more area. And of course remote Dimmable drivers in neat, vented box that suspends from the ceiling if so choose. With a Dimming knob, not a silly screwdriver that will break the plastic screw & mess up the driver.
I can get you a 25% discount on anything from Amare most likely. Just lmk!
They not recomended much here unless by someone who has used them & because the majority here are hung up on DIY or manufactured lights that cost as much as a fancy unit but are essentially DIY units, they've fought the facts for over 5 years now. LMFAO! Just to all just now begin to realize what I've been telling them for over 5 years now is true & they're all scrabeling to make the Amare spectrum or close buy spending even more $$$ on Enhancement strips that will never quite blend likea properly designed fixture with the proper spectrum already included & dispersed evenly throughout for maximum spectral blending.
You can lead a Camel to Water but you cant make them Drink.
Goodluck man!
Oh, & if trying to save money or purchase something less beafy, they now have the Bar-8-L (lightweight) & the Bar-8 UVL which will finall allow led a true Full spectrum. One that should beat the pants off CMH!
I'M Excited about it. It's 660w on a dimmer, remote drivers MW, folds or detaches in the center for x2, 330w bar lights. Will cost $1250 delivered to your door n thats just retail. Anyone who does buss. Directly with Amare/Victor rarely pays retail.
PRO-3 = 1-1.5 GPW / Bar-8 or 4 = 1.5 + GPW from my experience using these products with my grow style.
Peace!
