Lighting If you had $5000 to blow on leds for your room - what would you buy?

@pop22 I agree I used NGL sourcing parts for 2 diy... great to work with

Oh yeah they are fantastic. I get a great price on parts based on the quantity and they are only a few dollars cheaper than ngl. To see them catch your order and have cobs in your mailbox within 72 hours for a 4-5 dollar profit per cob is amazing.

If you do not DIY I would go with @Tasty the guy is miles ahead on the technology scene. The 335 watt light Iam running I wanted to purchase another he said hold off I have light coming out with the same light coverage but only 275 watts. Aluminum cover a heatsink to kill for LOL JK but still I would not buy with out giving TASTY a serious look over. He has some of the lowest prices for what you get on the market period.

I hate to have a negative conversation on the product you have worked hard on, this is why I wish we continued to talk when I first mentioned my concerns. My opinion is that the kits were absolutely a phenomenal price before prices began to plunge, now with the fairly new introduction to citizen cobs I believe Cree as a competitor is over priced.

This was also the sheet I brought to you on the other forum. My first concern was the sized heatsink is identical to the sst105 which is indeed rated for 35w.
understand the confusion when it's now said to cool over 50% more than its twin. Second part that I don't understand is this chart is rated at an 80% efficient source. 3590's driver at 1.4a are said to be 62% efficient which is 18% less then the chart states. Quick math suggests 59w not 73w but well within specs of your kit.

Based on chart 2 at 50 watts on an 80% efficient source it puts the heatsinks at 40c above ambient temps. 40c=104f and in a 78degree room now puts the heatsink temp at 182 degrees or closer to 200 degrees on a 62% efficient cob. This is much warmer than the sst120's which have a rating of 55w from ngl. I don't want anyone to be wrong here I just want to understand why my numbers are higher.

Hi @BigSm0

Thanks for your post. Prices on Cree LEDs have gone down - that said, Timber pricing has never been based on retail component pricing as we have always purchased at the levels we currently purchase at, and what our kits pricing are based upon. I understand there are lower priced solutions - and that is fine. We handle the top bin Cree CXB3590 as, again, they have been proven to produce great results. Our kits contain features that other companies do not such as 10 amp fused power inlets and waterproof electrical interconnects. Safety is always critical in the design and testing of all of our products.

The heatsink temps when measured with an infrared laser thermometer are 120-130 deg F after being in operation for greater than 15 minutes. This is the maximum we have measured. Of note, and something that we always recommend to LED users, is to run a small fan that blows air across the pins of the heatsinks. Doing so will reduce your ambient heat sink temps to 80-90 deg F. Most grow environments already have active air movement which is usually sufficient. Also worth noting, the thermodynamic cooling performance of the Cooliance Pin Heat sinks really excels above the competition when there is air moving across the pins as a result of their trademarked design.

I hope this helps to clear up any confusion.

Have a good evening.

Regards,
Dan

With fans the on them the temps do drop.

Of all the people here hearing you say your vote is for cobs is music to my ears. I have spent allot of time checking out their products and any company equipping their lights with cd-bin 3590's and meanwells is good in my book. I think the reason you see a few more votes for amare is the enhanced spectrum. 3500k cobs do a very good job vegging and flowering but the rings on amare give the spectrum that extra boost. Red,infrared, royal blue and daylight. The solar spec is equipped with an 18" t8 uv-b bulb which is said to increase resin production. @iampepe has proof on that! The pro series are a combination of tob bin cobs driven at higher amperages for deeper penetration and also equipped with Cree xp-G3 and xp-e2's monochromes. I'm all for white light but you should give enhanced white light a try.

I was just looking at Tasty LEDs just now, they have a t4-2100, 335w, maybe 7 of those. That would look pretty bad ass.
The amare sp900 is really nice, a few of those would be awesome!

I have a @Tasty t4-2100 335 watt 150 watt PAR for 670.00 U.S. that is one great light my man. Give him a shout and see what he has coming up in the next few weeks as far as lights go he said he switching to even newer tech as far as drivers and emitters I do believe but keeping the same price point. I swear the darn thing blows cool air compared to any other led I run he machines his own heat sinks too. He uses high grade aluminum for a cover and high end fans. It is a work of art IMO Total wattage: 335
Lumens: 42,060
PAR watts: 150
PPF: 690
Efficiency: 50%

Emitters: 4 CXB3590 3000K 90CRI 36v BD bin
Current: 2100ma
Watts each: 75

Power supply: Meanwell HLG series
Efficiency: 93-94%

AC Input (C13): 120-240 volts, 50/60Hz, .75amps at 120V
AC output (C14): for connecting multiple units

Dimensions: 6" x 4.5" x 36"

@BigSmO I hope one day to give them all a try keep up the great led work bro.

I have been running a 1200 watt COB

since September 2014 600 plus true watts she has been my workhorse surrounded by Apollo six's and cheap 300 watt panels I have grown a shit ton of good weed with that set up just not nearly as efficient as the newer tech

 

[F.N.]

I see 300 watt kits from timber for 629.00 and you have to put it together. Tasty for 670.00 comes fully assembled and 350 watts that is a no brainer. When a light gets complicated more things to go wrong down the road IMO

There is actually a big difference between the 2 kits. Tasty is running the cobs very hard close to 2.1amp to hit a higher wattage. Timber is running their cobs at 1.4amp. 4 cobs vs 6 in timber. I regularly build lights and suggest 8 cobs if the goal was 300 watts based on the fact that the lower the amperage re more efficient it would be. There is a 6% efficiency drop, shorter life span which shouldnt matter to much and your going from 167 lumens per watt down to 148 line a per watt.

To make things even better if you were to swap the Cree cobs for similar efficiency and go with citizen and just about cut timber price in half.
