Has Anyone Tried These New Type LED Bulbs?

I have noticed a slight evolution in LED's over past year which now include bulb in pic.

This particular one is 54w but they look so much more intense than the older ones. I gave up on LED's having previously tried them using multiple square LED panels of the previous generation LED's ie the smaller ones, and was totally unimpressed with the very weakly low yield plants they produced.

Has anyone tried them? I was thinking of doing an HPS v's these LED's comparison test in ebb and flow rockwool system!

Would prob go for one bulb per plant in a tray (one long tray) which would equate to 162w for the x3 plants !

If so, those are the newer Epistar emitter. They are good, but the cool and warm white ones kick the red and blue's ass in my testing. I have 1200w of the same series chip but in cool/warm white. And 1200w in the 30w version are stuck somewhere between Chicago and my home (been in Chicago since Tuesday), waiting on USPS. I'm hoping to get my new room done and going this weekend.

Yeah that's the same type in your link.

They vary as per led's per bulb with the one in the pic being with most led's (of this type) x18 that I have seen. Although the red/blue can vary with different combinations. I realise 54w is a quite a lot for led's but they are so much more intense than the previous gen ones. I am just thinking about the best way to do a 600w HPS v's these LED's comparison.though..

ATM my planned set up is an ebb and flow system with x 3 trays containing 3,2,3 plants and same again but with x6 54w LED bulbs (same nutes and reservoir for both! That give a nice 600w v's 324w comparison. Thoughts?

So nomofatum you honestly think white is better. Has anyone done a white v's red/blue LED like for like comparison grow yet then?

If you can solder:

Note, you want to power these chips at 2w, not 3w. At that power you get just north of 100lm/w and generate less heat.


The problem with bulbs is the mini driver in them will blow up within months, maybe a year if you are lucky.

Umm, can solder but won't get on with this if it gets too complicated !! Thanks for suggestion though. I'm more a plug and play kinda guy!

Look at the flood lights then. They have 10w-100w floodlights based on the same emitter, don't think they make red or blue though.

Edit: They do have red and blue.

Doesn't look like anyone has tried using those yet. Don't think i'm gonna be first to try, also they're super expensive!

I will try to find it, there is at least one guy who is obsessed with the floods, getting good results.
$90 for 100w is the first one I see, but I think I saw that as low as $70 before.

I'm using the 3w cool and warm white chips on the boards using the 100w power supplies I linked to. I'm waiting on a bunch of 30w COBs of the same emitter. I doubled my space. I can vouch for the 3w ones, waiting to try the 30w chips, hopefully tomorrow.

You got a link to the 30w chips? Also why did you go for white and not red/blue led combo?

Note there are some mistakes in the listing, it looks like they have specs from 50w mixed with the 30w.

I bought 50 red and 50 blue (3w), did a mini side by side, and red/blue got trashed by the whites. Then if you read the specs, the output of the whites is way higher, and it's almost all in usable wavelengths. You will notice a lot more white LED grow lights in the last 2 years, those are ending up being the better ones. This wasn't true a few years back, but is now.

OK those are a game changer! They're the same ones used in the floodlights !!! OK now my ears are pricked for sure.

So are the previous links still relevant for these chips which lets be honest must be super bright if one of them is used in $50+ floodlight!!

Pretty please, how would one go about a set up with those? thinking one per plant should suffice, no?

Also which white would/are you going for

Warm White - 28k 32k
Natural White - 40k - 45k
Cool White - 60k - 65k

I'm going to thermal adhesive them to 6ft pieces of aluminum, and use splice connectors to tap lamp cord to power each of them. If the damn things arrive today, I should be able to show you by the end of the weekend. You need them attached to a fairly large piece of aluminum or you will want a fan for cooling. I'm waiting for them to arrive so I can pick the width that will cover the back thermal plate, but not the power terminals.

I've only tried as low as 1 100w panel of the 3w ones, so can't say one per plant will cut it or not. I would try to quantify by lumens per sqft if I were you. 3000 = ok, 5000 = good, 7500+ = pro (getting into risky territory)

Nice move. I can see why you are going to try them. Would love to see the process mapped out. You should start a thread!

How many per plant are you going to do, also what power supply are you using per strip etc?

Also the aluminium strip makes sense.

Don't forget about my color range question on what white you're going to use and why!?

I may be going overkill, I'm putting 2400w total (1200 3w, 1200 30w) in 32 sqft. That puts me at almost exactly 7500 lumens per sqft, then I add two tanning bulbs for UVB.

Warm and Cool. Cool = more blues, Warm = more reds. I have a little bit more warm then cool. Don't get the neutral, it has less light in the usable spectrum. Cool will be your workhorse for veg, warm will help fill out the buds. Warm does decent in veg too, but only about 80% what cool does.

I'm doing a nutrient side by side by side once the room is ready. If folks like the results I will be starting that thread. Need the results or a thread like that will devolve into mindless monkeys throwing the words Chinese crap around.

All I have pictures of now is my halfway done pair of autos under one 100w panel.

Phar + Nomo you both need to get over into the Led section and into the DIY LED thread. Those LEDs you guys want to use are intense enough but not efficient enough and efficiency is king when growing with whites. Spectrum will only take you so far and marijuana wants an efficient light source to grow with, which is why we didn't use regular old light bulbs to grow with. They were intense enough but their efficiency sucked big time so they wouldn't grow plants. No name LEDs are just like that. You have to put extra energy into them to get out the your lumens and that means shit efficiency. A setup like this one pushing ~120 lumens per watt will outgrow anything you guys are talking about and is solderless too.

So that's 13.41 + 1.12 + 19.40 + 9.99 = 43.92 and you could probably get them for a bit cheaper if you looked around. So then all you need is an old extension cord, some Kapton tape or thermal paste to afix the LED and some wire nuts. The Vero 18 intergrated array performs much much better than those multi chip arrays and mystery diodes. China no-name whites don't really cut it guyz.

Edit Ooops I did forget the power for the fan which will work with almost any old 12 volt cell phone charger so that's free to a $5.00 increase in cost plus 2 more wire nuts.

You understand that makes no scientific sense right? The plant has no idea how efficient a bulb/led is. What they know is how much of the light they can use is hitting them. That is all that matters to the plant.

Twisted presumsions. This is the kind of thing I was talking about with my monkey comment. Not to call you a monkey.
