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

I stand corrected sir.
Though I see why one would be afraid of faulty wiring, after discovering wago 222 connectors I felt safer and my wiring is so much cleaner now. I find that being able to buy everything I need to grow from normal stores and avoiding the probably-under-surveillance growshop a lot easier on the ol'nerves.
You do make an interesting point and since I don't have access to both technologies I can't confirm or deny your remarks.
So the task of proving that what you say is true falls to you since you do have both.
Can you objectively measure and show the efficiency of both and how one is better than the other? I think we would all have a lot to gain from that.
 
Might be a noob question, but:

Does anyone know if the screw-in LEDs will work in a clamp-on reflector such as this:

I have some 8w soft white LEDs in the kitchen that say "800 lumens"...just wondering if they'd work as a stand-in for the two 42-watt CFLs I currently have in my reflector. Other than that reflector, I don't have any sockets for them so just curious. The reflector holds a standard E26 base bulb but I have a 2-way socket splitter in it so it can hold 2 bulbs.

Yes they will work fine. It's a standard socket. :tiphat:

I use 20 watt 2500 lumen bulbs in 5-in-1 adapters for most of my non-drug plants and ran a few micro dope grows with them as well. They do grow nice plants, but dealing with the sockets and wires etc is a lot of work. They're also inefficient compared to PCB type LED lights. Point is, you can post pictures of healthy frosty buds grown with ANY light, even shitty CFLs grow great looking bud. But LED spots are not the best lights around. Oh and I do indeed own quantum boards and will be buying more in the future, there really is no competition.
:laughing:
Nobody cares about electricity costs.

Quantity your dry yield from the same strain in comparable conditions.

Your quantum board cant even fit in my cabinet and my screw in 10 bulb setup is cheap as shit. Even a monkey could wire it up.

Your cab is less than 11 inches wide? That's a micro setup indeed. You'd gain headroom with PCBs. Wiring ten sockets and screwing bulbs Vs. Plugging in one power cable, and having more light than any E27 bulb could ever put out. I understand that DIY can be a fun way to pass time, but even then it would make more sense to build a fixture with LED strips.

psyphish, the whole point of this thread is evaluating SIL usage for a no frills, unexpensive, effective way of growing.

E27 sockets/cleats/multiplier/fixtures, wagos and SILs are commodity items, easily available, cheap and the easiest to build for most.

LED strips aren't as common as SILs, and cannot compete in convenience nor flexibility with SILs: replacing, unscrew to off, mix and match different temp colors, SIL wattages...

Whether quantum boards may be a superior solution in LED technology, no one is discussing that. We're researching and sharing results of our findings with commonly available SILs.

For reference sake, how much does a 100W vegging rig with quantum boards cost/need? And for flowering, say 200W?

A complete 135w kit (dimmable 60-150w) for 3x3 vegging costs 175$, less if you buy the board, heatsink and driver separately. You can flower a 2x3 with the same light. 6x20 watt E27 spots costs 120$ where I'm at, plus sockets, wiring etc. and I don't think I could veg a 3x3 with them.

I guess I could use cheaper lower wattage bulbs, but their LPW efficiency is pretty much the same as the higher wattage bulbs (125 LPW vs. 160-170~ of QB), if not less. There really aren't many choices on the E27 market.

You obviously have not read this thread thoroughly.

Read this post. I explicitly said this thread is NOT a thread about comparing screw-in LEDs to anything other than screw-in CFLs. It is not to be used to post about how much better COBs, Quantum boards or anything is better than screw-in LEDs. Again not point of this thread.

This thread was created to measure lumens from screw-in LEDs and screw-in CFLs. People are more than welcome to contribute either results from screw-in LED grows or any lumen measurements using screw-in LEDs, but 'xxxxx is better choice' is not welcome here.

very beautiful buds , but I see the bulbs are quite a distance away from the canopy... My grow area is ony 2.2 feet high. With bulbs installed I will only have 1.3 feet of height from pot/soil to the lights... Is a micro SOG doable ?
I know that a few pages back there were some LED, CFL etc distance charts but I can„t seem to find them.
At what distance should the canopy be from 10w LEDs? Sorry, I know this was asked before


2"-3" should be fine, maybe closer if need be
 
the sole purpose of the e27's are their costs.

people run can run 200watts for 50$

lets say they get 100gr yield, thats still a dollar a gram in total

if you slam the bulbs youll get 600hps intensity, and thats the golden standard for growing

ps a lot of these diy bulb growers are first timers (or at least still learning) why spend hundreds of dollars to find out you fucked up the plant?

You're right about the newbie aspect. I started with a 250w CFL and then moved to ceramic metal halides, screw in bulbs are definitely simpler for a beginner, especially heatwise.

I apologize about the "shitposting", I just get carried away sometimes.

This kind of post is why this is the only canna forum I read...:comfort:

Have to take pictures, but I'm afraid I recently found that's a little too close.

I had older pistils turn brown on ladies in 4th-5th flowering week: different strains, different tents, different nutes, but same lightning, SILs set to 3" from the canopy or so.

I raised the SILs to 6" and three days after that, I found the ladies entered a new bud/pistil shooting wave, all white and spotless.

I think propping them closer, say 3-4" helps to reduce stretch on first flowering weeks, but once is stretch is over having them too close will stress out the pistils. No bleaching however.

ALSO RUNNING DOWN THE MIDDLE OF THAT ROOM IS AN 1000 WATT HPS that is not turned on .

i may do a run with both after this one.

also looking at the 20 reptile e27 bulbs to supplement next

The reptile UVB bulbs are really useful in small projects, the plants smell more and have more trichomes. I wonder if we'll see UVB LED spots in the future, CFLs have such a limited range compared to the LEDs.

thanks


this is the better advice


I only ran these once and a few colas were around 2.5" from bulbs with no noticeable ill effect
