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

Scrogmonster I must say this is an awesome grow. I cannot believe how organized you are, my grow room is not...at all.

I was at everyone’s favorite cheap LED store, when I saw something interesting...

9w 800 lm Non-dimmable plastic globe

6.5w 800 lm Dimmable glass globe
View Image

9w 750 lm Non-dimmable plastic globe
View Image

9w 1100 lm Dimmable glass globe
View Image

Anyone else seeing the trend here? The dimmable glass globe versions are killing the non dimmable plastic ones we normally use. Is the increase in efficiency due to the glass globe or dimmable driver? The bases of the two bulbs look different, I wonder what kind of setup is inside?

11w 1500 lm dimmable glass globe is the best advertised efficiency I’ve seen yet @ 136.4 lm/w!

Edit: apparently this is what’s on the inside.

PCBuds - ha ha ha very funny. Not that any one doesn’t know but just in case... pics just got Turnt by uploading them haha.

Jellyfish - Thank you very much for the kind words my friend. If you check out my journal in my signature, some where in there you’ll find an explanation of my training style.... but basically I kept topping and lollipoping and topping more and tying everything down to be even during veg then when each plant had 24 tops I lollipopped those till I was ready to flip them maybe just a week.. week n a half.

I’mone Thanks! I try my best to keep things neat but I’m never satisfied lol.

ScrogMonster you are doing an amazing job with those plants! Resin production and overall flower photo quality looks on par with the best of the best :tiphat: overall setup winning :)

frugal minds UNITE! ID love to rub a joint on those flowers omfg!

Oh dude... you know I hadn’t thought of that but I won’t forget. I better roll me joint in the next two weeks and I’m gonna coat the outside in as much live resin off those close frosty trim leaves as possible! :) I’m glad you said that.

The night before harvest soon after Christmas the stoner rubbed live resin all over his spliff. He inhaled and exhaled and savored the flavor. With his next drag he smiled and sagged and silently gave thanks to his friends from ICMag.

These girls are about 8wks into flower now. All 5000k all the way. Don’t think I’ll have any 2700k in any of my sockets ever again.

I might let them go one more week as I’m not seeing even ten percent amber. These pics are from a few days ago but most of all three strains trichs are almost all cloudy at this point with the Tangelo showing maybe 2-5% amber, just a few here and there.

Wow, i have 2/3rds of 2700 k bulbs I will switch to 5000s. Do you use the great value bulbs with the plastic globes? I notice some of my cfls are 6000k do I need to use those to supplement?

These are what I use. I been getting from costco at only 3.99 per 4pack. There is an electric company instant rebate that saves at $10 per pack. I really need to go get more and stock these up while this rebate is still good. Limit 3 boxes per customer per day.

They’re not as efficient as some newer ones but they’re 90 CRI and I really like them.

I got some great value 14 or 15w and.... I’m not sure what it is about them other then it’s a tighter smaller cluster of chips but I just don’t like them as much.

I have some great value bulbs that I took th cover off. They are now making purple light? My latest bulb purchase was Phillips 100 watt dimable. They have glass globes. Some are 5000 k most are not.

My poor tablet won't let me load any more apps. Adding the light meter will have to wait a minute.

Does anybody here still use the big curly bulbs that were rated 43-45 watts? I grew some big buds with those bulbs, then I switched to LED's. But now I'm starting to realize the CFL's were giving me greater yields!
I had a flower room that was rocking 8 of those curly monsters, giving off negligible heat and growing some big ass buds. I think I might go back to those days. What do y'all think?

That's weird. Maybe they're burning out in some strange way?

I say smash one to find out what kind of guts are inside.

They may not have LEDs that protrude into the globe area.
Then you would have directional SILs.

I have been using them and switched to LEDs after reading this thread. A couple of plants are still under cfls. It seems they get a weird reverse taco thing, I'm trying to figure out why.

Ok you are not a good role model. I smashed a light bulb and the LEDs stick I into the bulb area. So what does that mean? Do I have to replace them all?

No, it's not like that at all. I'm thinking of going back because I think I got better yields! Those 23 watters are only good for vegging as I recall.

Sorry, I like to break stuff.

I think you've just got multi-directional bulbs so not much point in breaking them all.

I'm speculating that being as the LEDs are in the globe, that the glass globe can be more transparent and still diffuse the light enough.
Perhaps that's why they have more lumens/Watt?

Removing the glass may not let too much more light through and it's beaming all over anyway.

I don't know how many bulbs you need but they're only a buck apiece.

I still think you should use the glass ones as side lighting and get more plastic bulbs.

It looks like we both bought the wrong color anyway. Lol 😆

i'll vet this to some extent
bud density with cfls can be killer dense
trade is more distance adjustments, but get 'em close and buds respond
still, for wattage leds give better yields
