Not yet. I got so wrapped up in replacing them in the house, I forgot my original project hahaYou got pics of the full light bar yet with all the outlets?
I think you glanced at the mA instead of the lu in your reference. Unfortunately, still under 100lm/W but a lot cooler in my small 4x4 momma/clone room.nice thats the first 9W bulb ive seen rated over 100 lm/w. are those the blue and white boxes from home depot?
these are about all the same from what ive seen, only advantage so far is the feit seems to have a metal housing as opposed to plasticThey get hot as fuck. It really sucks. But I doubt any other bulbs get that much less heat coming off them
Why are you messing with this junk rather than starting from raw components?moral of story:
1.daylight/cool white is slightly more efficient than warm white (duh)
2. brightness/efficiency was as expected per product specs - quick math on stated lumens per watt on the box seems valid even if you rip off the reflectors
3. "can opener" reflectors were useless though the angelinas worked pretty great
4. kill-a-watt on a single bulb <20W isnt all that accurate and or useful
future work:
-i hacked apart one of my 100W brightsticks and skewered the board upside down on another brightstick and lit em up. both lit up from one driver pushing both boards in parallel - pulled same 14 W. presumably this would cut the current in half to each board and could be a 10-20% efficiency bump? im gonna sacrifice a bunch of the 5K feit boards , mount em on a real heatsink and test them with a single factory cheapie driver pushing 1,2,3, and 4 boards each. also see the difference in cheapie driver vs a 90+% efficient meanwell. i expect better luminosity by more efficient cooling alone, yet alone reduced current
The acid test will be 4 of the 15W bulbs ($20 including driver) vs a 3590 at 60W ($50-55 including driver). waiting on my bjb holders for the citis and gonna do the cob tests all at once later in the week
time to buy a real benchtop power supply....
science brah. i love off the shelf stuff for the growers still using CFLs. also these make awesome cheap supplemental lighting when you gotta light up a clone tray or two or want to dick with your spectrum.Why are you messing with this junk rather than starting from raw components?
that store is a solid one stop shop
I might buy those Utilitechs ($2.98/2) to take apart, clip the wires off the metal mogul threads, mount them on a heatsink and wire them all up in series to a power cord to rebuild my hoods. That's cheaper than buying another driver and some say. ...2540's or so. Just use a new white tub as the reflector, cut the bottom out and screw it to the heatsink. I imagine these leds just need direct ac power unlike chips that need a driver, right?science brah. i love off the shelf stuff for the growers still using CFLs. also these make awesome cheap supplemental lighting when you gotta light up a clone tray or two or want to dick with your spectrum.
i got cobs out the ass over here. 3000/3500/4000/5000/6500k 3590s, 2700/5000 70 cri/5000 80 cri citizens, 135W and 275W cutter, shitload of photo red and far red monos, old ass ufos that need scavenged, etc etc..
and still have more gear/rooms than i can fill right now. idle shit all over the place
really my only three goals for the week are:
1. real world test of the citi 1825 series next to a 3590 to get a benchmark of its efficiency and value vs a well-understood control
2. real world test of the cutter cobs next to a 3590 to get a benchmark of their efficiency and value vs a well-understood control
3. mess with these $0.30/W off-the shelf A19s so we can get a rough idea where they fit in the grand scheme of things. are they 110 lm/W off the shelf? 120-130 lm/W when you rip the diffusers off? etc.
takin it for the team, trying to fill in the knowledge by doing things nobody else is. do you really want to see another boring 3590 rig built?
id have more cob rigs if id stop fucking breaking 4-40 taps grrrrr.
a lot of the boards say 94V, pretty sure all diodes run on DC but i could be wrong. i think the fact that a lot of the boards are designed to run on 94V is its easy to get there from the usual 115-120V ACI might buy those Utilitechs ($2.98/2) to take apart, clip the wires off the metal mogul threads, mount them on a heatsink and wire them all up in series to a power cord to rebuild my hoods.

Damn looks like I can't do it then.haha I will be building some nrlew and improved hoods like you've seen of mine before, but with a heatsink on top and 2540's rather than a baking pan and moguls with Y splitters.a lot of the boards say 94V, pretty sure all diodes run on DC but i could be wrong. i think the fact that a lot of the boards are designed to run on 94V is its easy to get there from the usual 115-120V AC
lemme blow some up on the bench and ill let you know lol
heres a brightstik driver... lots going on in there... looks like a simple AC>semi-regulated DC power circuit. i cant diss it those are some fat ass caps. im sure its pushin 80%+ eff.
