Off the shelf retail store screw-in LED and CFL bulb comparisons

[mexcurandero420]

These are my SIL plants...
4700 lumens total.
The lights can be closer once the plants get bigger.

Dark Devil F2 x Sugar Black Rose feminized auto seeds...

What is that "Edison bulb" on the first pic for?

Heating? Or some far-red/infra-red source?

At the back end of last year, Migro had his ppfd and spectrometer under some lamps https://www.youtube.com/watch?v=XnIzB_8knLU
Phillips 13.5w 100w equivalent warm white. Using 1.5 lamps per foot, he gained a third more light cutting off the dome to average 400ppfd from 1.78ppfd per watt.

You will get 50% more out of a 301 light, but it's still above many entry level lights

Looking at the Samsung based lamps from other manufactures using 9.5w to create the 100w equivalent, they are really very good.

I'm not sure about the diodes, but the brand V-tac uses samsung driver chips, and has up to160lm/W bulbs (evolution series)

Hey guys whats good!

My idea is to pop many seeds and reveg the ones I like the most for future grows in bigger areas.

Its a dark propagator 90 tent (90x60x90 height/3x2x3 height).

12 x 15w 6400K bulbs, the brand is Espartan and its said to put out 1480 lumens each.

So 180w. Never flowered under leds (only used a few SIL for mother plants) so I'm eager to see the results.

It's 24 seeds in 2l pots.

Cheers.

That's the guys. People in eastern europe get the good ones but most of us are still stuck in the dark ages.

V-TAC has signed an agreement for delivery of LED chips and components with SAMSUNG. Since the start of 2018, a change of the product range with products from the V-TAC PRO series, has been initiated which have been manufactured with Samsung LED chips and are offered with a warranty period of 5-years.

I have learnt V-TAC don't use Samsung LED's in the 160lm/w range.

Just a pic of some ASDA lamps I don't want leaves falling in

Oh wow that's a clever way of cutting the domes! The plastic on those looks a lot thinner than the phillips bulbs i have

 

[f-e]

If we think of them as tulips I cut one leaf out first. Making the two vertical incisions starting from the top, then tried to fold the leaf out, in doing so the entire bulb jumped off. I was then able to make the third cut with good scissors. Moving on a leaf, no issue. By the third leaf the dome had no strength for me to make an incision without folding. So, I placed the dome over a 15mm pipe. This supported the center of the dome so I could carry on jabbing the knife in without the dome creasing.

I used a Stanley Knife and CK 92001 combat scissors.
I had expected to use a rotary tool such as a Dremel but couldn't be arsed to get up and fetch it

 

[q3corn]

An elaborate answer! Sounds like a lot more work than just popping the tops of to me, lol.

 

[f-e]

I came across some today that were tougher. I had to scalp them, drilling a 5mm hole then running around with my jigsaw. Then I pulled the 15mm of bulb off that still remained. Before going back to the scalp to scissor it into a cross, which actually stayed in place quite happily without any sort of glue. After a slow start, I was doing a lamp in about 3 minutes.

I have to have a guard as they are going on the floor pointing upwards. I once had a 50w there with a greenhouse tape cover that put a hole in the tape when a leaf settled on it. I don't want to toast an LED

You can see which one's I did first

4 buttons to upload, but non to add the 50w from my album
