spectrum guys 200 watt fixture

I am in the market for more led power, one way or another. I started with the magnumplus, then add the magnumplus2, and now was able to use the Sol9 900 watt panel. The mag+ is over 3 years old with continues use ( they quickly sent me new 2 new power supplies when needed), the mag+2 was rebuilt into a larger housing within a month of receiving ( just now is needing a power supply and mailing in tomorrow), and the Sol9, due to disagreement with buyer, is gone with less than 5 months testing. The Sol9 did loss 1 and a half chipset in 4 months. The light did show promise, though my first try at dwc and rockwool cubes was a mess, trying to adjust ph with the drops. I did have 4 in coco that even with the bad ph, averaged 26 grams per plant ( they were sitting in 2g bags at the edge of a 5'x5' area, full that would be 16 to 23 2g bags).
Now I like to watch ledmagazine.com's product and news section. Semlight has an outdoor floodlight that is 4 50 watt bridgelux or cree chipsets, 110-130 lm/w. The colors are warm white, daylight, and pure white. And the use meanwell drivers. I was thinking the 2 outer chips warm white, and the middle one daylight and one pure white. What do you think?
All top quality components. I would still tear it down and make sure I'm happy. But for under $400.

I will fix the link in a minute.

Same, just longer with 4 COBs.

The sales rep I'm typing to, was wandering if the lack of UV makes a difference. If you are using the Vero's, they don't have any UV, right?

Nobody?

Yeah we've been talking about using those tunnel led floodlights for some time now. Problem is how can you trust the specs given??. You think their using REAL vero cobs???? IDK tough call

$400 shipped for 200watts of vero is a red flag IMO @ a profit.......don't think their using high quality cobs

You had problem with HGL's SOL panel/customer service??? ...........BIG SHOCKER,lol

Honestly, they have already sent me the replacements within a week. But after digging deep into Google, I found that Hydrogrow doesn't even have a pat. pending on their cob spectrum. And I can't find who makes the chip either. I really like the potential of the unit. The light distribution is excellent. That is why I like the COB's. I am waiting for them to send me specs on the 2 different chipset efficiencies. If I didn't find this in ledmagazine.com, I would be very skeptical too. She quoted me $300 with 90-100lm/w or $380 with 110-130lm/w. That may not include shipping. They said they would build my a sample with 2 warm, and a daylight and pure white. Do you think 2 warm and 2 daylight would be better? If I this has what they say, then this would be a great price, right?

The COBs in that thing are square so it's not Vero (which are round). Probably it are China-assembled multi-arrays with chinese phosphor and if they are telling the truth Bridgelux dies. I don't know the difference between pure white and daylight, but for flowering 3 warm (2700-3000K) to 1 cool (5000-6500K) works well. If you decide to use them then remove the glass cover for some extra light.

Just got an email from China. The 110-130lm/w are bridgelux and meanwell drivers (26000lm) and the 90-100lm/w are epistar with their drivers (20,000lm). that's a 60 watt different for the same lumen output. Bridgelux is down the road, so I will give them a call to verify what leds Semlights is using or if they even sell to them.
The color temps are:
WW- 3000k-3500k
NW- 4000k-4500k
PW- 5500k-6000k
So I'm guessing you aren't using any uv/ir right, MrFlux?

I have had to do some changes again to my room. It was to hard to reach across a 4x4 tray. My room is 5'x9'x9' ceiling. I am now using a 3'x3' next to a 2'x4' next to another 2'x4'. I have put the mag+ over the 3'x3' tray with a DWC with 2 plants in one bucket and a 2g bag with soil. The mag+2 has 3 new housings to fit the 2'x4' tray better. Here I have 4 Purple Creams in 2g bags. The last tray is empty until I get more lighting. If Bridgelux verifies they sell 50 watt COBs to Semlight, then I will start with 2 over the last 2'x4' tray.

Still waiting for an answer from Bridgelux on the COBs. Thinking that I might run one semlight (200w) and 2 of my white fixtures (110w X2) over the 3'x3' tray. After seeing MrFlux's grow with possibly the same but lower wattage COB's. I'm looking to get 5, after verifying they are the leds I want. Worst case I use the to light up my shop.

Dam holidays. Still waiting to hear back from China. I did ask her why the COBs aren't round and if they where the Veros. I looked at epistar and I am almost sure that is what is in the photo.
Had to dip all the plants in neems oil.

My guess is this floodlight grows better than most dedicated growlights out there. To get better than this would require more money, or you would have to build it yourself. So it looks like a good deal. But 200W with passive cooling will get hot so keep the air flowing around it. Bridgelux sells their chips (the little squares inside the yellow phosphor) to distributors and such, they will not really be able to tell you if this light uses their chips.

About UV and IR, no I don't use that; I believe the benefits of UV can be had with extreme blue light (~450nm), without the oxidization.

If your so interested in using a highbay/tunnel/flood light fixture why not go with an ALL cree built panel.

http://www.cree.com/Lighting/Products/Indoor/High-Low-Bay/CXB-Series don't know the cobs their using, but it's at (REAL) 100lm/w of straight 4000k. Great from start to finish..........I think

under $400 with a 10yr warranty, can even find it cheaper without the reflector($50-75 extra option)

I do like that light, but it's at the same price point as this with all 3 color temps. Also this with bridgelux would still put out 3000 more lumens at 200W (compare to 230w).
MrFlux- What was your cost for 300 watts of Veros and drivers?
I also inquired about the new Veros that are coming in June. The will soon be made as a sealed and lensed outdoor application. I couldn't find anything on what lens angle will be available, but Lensed Vero19s would be. I'm sure that would bring the price up a little, but would still be under $500. I also inquired about just the casing, to fill with my own COBs.

Vero's are about half a dollar per Watt, mean well drivers about 35 cents per Watt. If you are tempted to go DIY check out this, it has the very easy COB+CPU cooler design with a good choice of components.

That would be the Bridgelux OLM series. It's two vero's inside a casing with a plastic lens in front. The plastic lens is exactly what you do not want: The OLM is doing 112 lm/W while the bare Vero has 129 lm/W (both 4000K), meaning a light loss of 13% because of the plastic.

Thanks MrFlux, I didn't see that info when I was on there site. I would love to see the Par # with and without the lenses. I have been pushing my friends store to get a Parmeter to have as a rental.

Almost have my room redone, again. The 3'x3' table now sits empty and the two 2'x4' trays are filled with about 350w over each. The taller plants are now netted. I really like this new bungie cord netting. Gentler on the plants than the plastic. The light mover is over the tall plants. I also add more power to the intake side, to compensate for the new 8" exhaust fan. The benches are stronger and attached to the walls. Now I can safely stand on the trays. The pics of the wiring would normally scare most electritians, until you read the draw (less than 700 watts). I now have the 50g. res. sitting an concrete, to help maintain res. temps. And that light mover is sitting on crossbars, so I can easily move it in any direction.

oops.

So, it's not the Vero's. It is bridgelux chips, but COBed in China. I'm still considering 3 to test. But also looking around some more.
