King Brite "angelinas". They really would be so perfect.

Here's a good thing for DIY reflectors. I use the smallest rectangular ones for 13w CFL reflectors. I modify the shape somewhat by bending and cutting, pull the sides out to make them rounder, cut slits in the front corners and bend the front flap up some. The slits also allow ventilation. I flatten out the ridges on the sides some too. The baking section has all you need for reflectors. I use the 13w ones for 5 minute end-of-day red supplementation to keep stretch down, using red "party" CFLs. You can also add side flaps for more reflection with aluminum foil clipped on with alligator clips. Look at that premium turkey one on the left. That's the Excelsior model reflector.

Great ideas man! I tell you as funny as it sounds my little girls under the ge bright sticks are doing phenomenal. I'd say right up with the 800$ grow lights in another room. Plus these inexpensive projects are a blast and the reward is twice as sweet. I spent 60$ on the bright sticks, power strip, socket adapters, and 3/4 copper for the light stand. It's adjustable, collapsable, and fun as fuck to build.

The Ikea Ryets are good LED bulbs. You can snap the diffuser off easily and the parts inside are easy to take apart because the driver part just plugs into the LED plate part. I mention this because the cooling of these bulbs is very bad, so if you had some time on your hands you could mount the plates on a piece of aluminum.

hey hey, new kid in town!
just got back from walmart and they had 4 packs of sylvania/osram "100W" 2700Ks for $25.xx - under $7 a bulb for osram not too shabby. i think they are 14W/1500 lumens or 15W/1600 lumens (>100lm/W is my filter on these, only the "100W" replacements seem to hit it, the 60 and 75W are just under. Its easy stoner math under pressure in the store
)
will test and report. soon as i can get it set up, i have the following to test:
A19s:
Feit 15ishW 5000K
Philips 14ishW 2700K
Osram 14ishW 2700K
GE 14ishW brightstik 5000k
GE 9ishW brightstik 5000K
cobs:
3590 5000K DB
3590 3500K CD
3590 3000K CB
cutter 135W 3500K
cutter 275W 3500K
i know the cobs vs the A19s are kinda apples and oranges but if im gonna set up a 'control' test setup ill run em all at once for par and spectrum. obviously the 3590s are well researched so that will be our control for each different CCT

no shit i have yet to see a single one of these that wont burn you. i think when i do the test described above the A19s with metal housings (feit) might pull ahead of the others which i believe are all plastic

one 14 watter crushes my clone machines with dense vigorous growth. i let some run too long and theyre stocky lil monsters but i have zero doubt that with the right CCT and array #/spacing these would be as good as anything out there, the cutting edge cobs not withstanding

The GE ones get incredibly hot. I saw a video about them. Actually probably the last brand you'd want to get. Always good to view a "teardown" video of a bulb before buying.

osram/sylvania datasheet:
https://assets.sylvania.com/assets/Documents/RETRO084.d3ba5cb9-0a99-4860-a1b5-9bc2fef9994f.pdf
pics soon. reflector was easy to remove. base is thick plastic (horrible for heat dissipation of course)
i might experiment with drilling/slotting the base on these to improve cooling.

They get hot as fuck. It really sucks. But I doubt any other bulbs get that much less heat coming off them

ok some pics on the osrams. heres the easy way to remove the diffusers if you dont care about destroying them. grab em with a big channel lock in 4 places and you crack the bond from the diffuser and the fixture without nicking up the plastic on the fixture by prying
ghetto 'can opener' reflector:
modifying an angelina
reflector below fixture, would need attached:
reflector hanging above fixture, no mounting necessary when used vertically
ill have to experiment with which gives a better pattern. cutting up that angelina increased the cost of the fixture by 50%, I need some kingbrite cheapies!

How many lumens or more imprtant PPF do you think those are realistically putting out and how many watts are they?

Oh man... that is such a great idea honestly. Those osram have a ton of diodes.ok some pics on the osrams. heres the easy way to remove the diffusers if you dont care about destroying them. grab em with a big channel lock in 4 places and you crack the bond from the diffuser and the fixture without nicking up the plastic on the fixture by prying

How did you cut the Ghetto reflector from the diffuser? A can opener really? You didn't use channel locks on that one did you?ok some pics on the osrams. heres the easy way to remove the diffusers if you dont care about destroying them. grab em with a big channel lock in 4 places and you crack the bond from the diffuser and the fixture without nicking up the plastic on the fixture by prying

they are 14W and advertise 1500 lumens but i think thats with the diffuser. hoping for 120-140 lm/W. im gonna measure all these against the cob controls above so wont be an exact science, but those are well understood so i hope to be able to draw some rough parallels. will be using a li-cor to measure ppfd and an ocean optics spectrometer for spectrum
those ones are for 3590s i had them on hand. i would think there may be some out there for cobs with a larger LES? this osram bulb could use a reflector for a 1.8-2" cob.
heres the one i modded:

heres all the ones they have (have fun!):
http://www.ledil.com/products/
cutter has them, theyre also on ebay. jerry at kingbrite allegedly has similar (same?) ones for cheapre tho ive never een them. took me less than 5 min to mod one with a utility knife
naw i used a utility knife. did not use channel locks on that one, in fact its easiest if not removed, the glue helps keep it from spinning when cut. i removed it by prying then snapped it back on, which it did, but it would spin around which made cutting it difficult/dangerous as my hand literally had to be on the diffuser to keep it from spinning, instead of keeping more distance from the blade

I see. Very cool. And Jerry does have cheapo reflectors. 88 cents cheap!
I used them on my light. They're no different then ledil besides being wider and the lines go horizontally on the inside rather than vertically like angelina.
