Indus from RapidLED

I already have the Onyx Bloom which is a good light. I have had it for a couple of grows now and it's efficient and produces some dense buds! Now I check on RapidLEDs website today and see that they have a new model light coming out. The Indus 10 and 20...

The Indus 20 light bars measure 112w actual draw, and the option to add the Red bar seems handy. This seems like an interesting idea, especially at the price it's at and its DIMMABLE!...

seems like RapidLED is expanding their options for the market. The website says these won't be available till the end of this month, but it comes at a good time and a really good price which is why I went for quality and $ factor in the first place!

I am also shamelessly using this thread to show some of said dense nugs

Specs of the Indus 20 for you lazy folks

Included hardware:

• 20 CREE XP-L (white) or XP-E (660nm red) LEDs
• 20 x 60 degree secondary lenses (40 and 80 degree lenses can be substituted upon request)
• Two LDD-1500L drivers (LDD-1000H will be used on bars with red LEDs)
• One LDD-H-4 board
• One NES-350-36 power supply with power cord
• 20" anodized heatsink with end caps
• Hanging Kit
• Splash Guard

Tech specs:

• Dimensions: 3.5" (wide) x 20" (long) x 3.25" (tall)
• Total wattage: ~120 for white units, ~70 for red units
• Input AC: 90-264V (there is a switch on the side of the power supply, please select the approrpriate input voltage before applying power)
• Weight: 6.75 lbs (light bar only)
• Maximum PAR: ~950 (at 18" height on Veg units)
• Dimming signal: 2.6-5.5VDC PWM, otherwise the unit will run at 100% intensity
• Cool White LED part number: XPLAWT-00-0000-0000V5051
• Warm White LED part number: XPLAWT-00-0000-000LU60E7
• Photo Red LED part number: XPEPHR-L1-0000-00801

Found some Par charts, dang I'm good

Rapid offers an interesting product, something I haven't seen done before with LEDS: a long, skinny bar of light. It reminds me a little of what the BML spyder offers except instead of multiple bars, you get just one. Hmm.

So my calculations give the Indus 20 ($300) around 80W of LED output, with the Indus 10 ($200) producing around 40W LED output (white units). The red units offer far less output and are equipped with 3W chips. I don't believe one can have a bar with a mix up of the two color options.

I couldn't help but notice that the driver is a separate entity and is not built in to the bar. Who the fuck wants to dangle wires around their grow op? I'm not impressed with the proposed spaghetti wire layout that they offer.

It being dimmable is nice but not necessary. I actually believe dimming to be quite overrated but that's my take due to my own experiences with alternative options. Additionally, the dimming capability isn't apart of the fixture's cost; you have to buy an additional device ($65~100) in order to dim.

The maximum par is impressive but doesn't really mean much, as there are so many other variables that come into play; what happens when the PAR sensor is moved an inch away from the 950 umol mark? Does it drop off to 100 PAR due to the light's structure? My point is that they don't offer the information that I believe is necessary to establish legitimate credibility. It's the same thing with the cheapo non-brand LED/Purple lights that have flooded the market; they claim 600-900W but pull half or less with a bunch of heat being emitted instead of light.

All in all, I think it's great that Rapid is trying out a new hat with this Indus. It's cool that they are using Cree technology and are cooling the LEDS passively. In the end, I don't get the impression that Rapid is truly trying to sell us, the consumers, a fair deal. There seems to be a lack of transparency between them and us; ideally they would share more data with us, which that I'm certain they have, instead of providing tid-bits.

I don't think this is the LED fixture of the year, by any stretch; I'm confident we, as growers, will see an even kinkier fixture in the near future.. something that will put this Indus to shame.

This is the light I posted about a couple weeks ago. They will also have a 40" and I want to say another intermediate option. Maybe a 30". I posted a bare bones pic of the light. My buddy Dxe will be testing them. They are just using LED modules for their off-road light bars.

Oh and not sure if it's been. Mentioned but from what I took from Dxe is that you can swap out some of The modules to just mix in more red if you'd like.

There are a couple pics in there.

Totally agreed. I don't like the design and it's also very inefficient. In an other thread I stated ~84% efficiency but it'll be even lower especially if the NES supply isn't fully loaded. Based on the data from RapidLED (20x XP-L@1500mA and 120W input) I'd say ~78%. Overall efficiency of the whole unit is less than 30% and even lower with photo reds. I am also wondering what are the temps like as the HS doesn't extra beefy to me.
