Fuckin weird my text gets deleted when I post that link. Anyways. ...
These are interesting and made just how wed want them to be made. So cheap... I might buy a few just to add to the outsides of my perimeter.

anybody else annoyed by marketers calling blurple full spectrum?

A few of the ones I posted links to actually do have white chips in them too though, which I haven't seen before. Very interesting. Looks like 2700 & 5000 or something close to that.

Yeah they do have white diodes but only a a few and are out shined by the blurple by a wide margin. Honestly i think the only reason the very few white diodes are in there is so the sellers can claim full spectrum even though the little amount of white will have almost zero effect on the growth.

ok so i ripped apart one of the 14W 5000K Feits, its actually got great build quality. all screwed together with a solid aluminum body acceptable for modding. that aluminum body is 57g! way better than the other plastic competitors. could easily take a cob... but which one? kind of need an adapter plate to go underneath it to fill in the holes (beer can? lol gimme some hacktackular ideas). heres the disassembled fixture with leads soldered separately to the board and driver (hard to see in the pic but i used black heatshrink on the ends of those red and white leads that go to the driver board in the mogul base)

upload_2016-9-23_19-20-53.png

heres what the driver puts out. remember the bulb assembly is 14W at the wall, it actually gives 13.05W to the OG board which is pretty damn efficient for a cheap board. its obviously an unregulated power supply, but heres what it did when i hooked it up to various cobs. lit em all up. nominal voltages from 36-100V. open circuit voltage on that driver was like 170ish V

upload_2016-9-23_19-30-20.png

so best driver utility is a 72V or 100V cob (actually overdriven in the latter case at what effect to the driver who knows) keep in mind that most of those cobs are 180-200 lm/W at 200-300 mA, so if that driver is 90% efficient lets party! I'll have to confirm driver efficiencies at various cob voltages later with a watts up (which only has 1V resolution so tough to get great data but we might learn something)

the OG board isnt much thicker than a cob so i might just mount one to it- however in this case the board radiates a lot of its heat to the outer edge of the case so it would be best to have a 42-50 mm disc to sit in there and mount a cob to that

upload_2016-9-23_19-28-9.png


in any case its all academic. now that i know the driver is 90% efficient ive got a lot more confidence in the original design with the (21) 3mm x7mm SMDs and am less motivated to modify. certainly with the diffusers removed they throw down their $5 worth and then some. Im covering a 5 x 2 veg area with 8 x 14W on a 12-slot power strip and its working fine. you wanna dim for babies? pull 2 bulbs. easy peasy

these Walmart greatvalue brand are the nuts, sku 681131132633

https://www.walmart.com/ip/Great-Value-GVRLA1427ND4-Great-Value-LED-Light-Bulbs-100W-Soft-White-20K-4-Pack/51497409

https://www.ebay.com/p/?iid=331913147340&lpid=82&&&ul_noapp=true&chn=ps

if you understand how 2700k is at a penalty on lumens, its exceptional that these put out 1600 lumens at 15W in that spectrum (with the covers on). They really pack a punch for $7 and the base/heatsinks are some of the best ive seen in a cheap non-dimmable bulb, they are metal, heavy, and have a corrugated/finned shape as well. Theyre also rated for 18 years, most of the other A19s under $7 are rated for 9 or 10 years (probably because they run hot as balls). these are def cooler to the touch than the other ones they are next to. i can actually touch them for a few seconds where the other ones burn my hand

im having great success mixing 1:1 with 5000k and 2700k A19 for ad-hoc seedling setups. growth is great and much better than 2700k alone. (it seems these A19 bulbs are only really available in 5000k cool and 2700k soft/warm white. shame as 3500 or 4000k would crush for veg. these were raised in 2.5" blocks from cuts, i just stuck them on hugo blocks today. these super sours were literally in a tray on top of my guest bathroom sink with 2 A19s stuck in the wall socket pointing sideways at them with a white foamboard behind them to reflect. less than $20 setup and as low tech as it gets i didnt even have a fan on them

Hyperikon 16W LED Light Bulb A21, 16W (100W Equivalent) (@ amazon)

1580 Lumens, 2700K (Warm White), CRI92
1600 Lumens, 3000K (Soft White Glow), CRI95
1620 Lumens, 4000K (Daylight Glow), CRI92
1640 Lumens, 5000K (Crystal White Glow), CRI95

Nice product. Good warranty, high CRI. The plastic globe pops off with a firm twist (careful, sharp edge). The neck warms up to around 75c. (ambient around 68f). You can use an "Ideal" reflector (for 3590) sand away the inside slots (drill w/sanding drum); then hang it on the bulb's neck like it was designed that way.

@ wall 13.4 watts. (122 lumens per watt for the 5k @ 95 CRI. Not sure if removing the white globe bumps that up)

They're dimmable -- for clones or veg to flower; tweaking color temp. If they were dismantled and properly cooled, might up the lumens/watts a bit. Though the advertised lumens may be while cool, at startup.

Great thread btw.

Also, check out their T8 CFL tube replacements -- nice vertical lighting or for low profile shelving

FYI if anyone is interested in messing with the GE Bright Stik 60w, Home Depot has the 3 pack for $1.80 clearance, YMMV of course since I stopped by two and only one had them available.
Certainly can't beat the price for some supplemental lighting or keeping clones, etc.
peace - Ro

Plenty of them here. I snapped this a week ago.

Could you put a bunch of these in a socket splitter and actually flower with them?

Was thinking 4 sockets, each with a 5 / 7 socket splitter (28 blubs). Should be doable for a 2x2 or at most a 3x3 (maybe add a middle socket for 35 bulbs)

When considering dimmers; standard Lutron dimmers are limited between 100 -- 150 watts per switch; table top or wall switch. Can add several dimmers for larger arrays. Split up the color spectrum to customize light. These dimmers won't provide max output when dialed to 100%. But, there may be advantages to under-driving bulbs, less heat, longer life etc.. And, with several kelvin values, tune light for limiting stretch, then shifting to warm light for encourage bud development.. You can easily over-light a small grow area.

They generate heat, driver is integrated. Heat management required.

My HD only had the 2850k bulbs, kinda wish they had the daylight ones so I could use them to build a veg setup.
