Testing Hans panel: 56watt Cree xp-e/ Lumiled rebel power==== Let's talk efficiency

His DIY fixture had ~ 40% 660s, but he replaced most of them with more NWs, and is loving the veg results. One ~ 6" wide fixture is doing a very nice job covering a 20 x 30.

As I have been saying for a long time, the future was/is in NWs, and now that they light a bigger area, well...

Companies like www.rapidled.com make solderless kits that allows you to select the diode spectrums @< $2/watt

Pet,I'm using the specialty lamps and fairly happy with T5 but just looking for a way to cut down on electricity and heat.Heat is more of a issue for me in a sealed cabinet and in the hot weather I could use a small air conditioner but that just adds to the electric bill.LED looks like it could solve both issues,especially if the drivers could be outside the cabinet.Buying LED units seem to be falling around $100 a square foot for quality.I don't want to buy cheap ones and end up with problems down the road.I'm interested in the DIY from RAPIDLED and I have soldering skills but I would need help with design.Do you have a idea of cost per sqft to DIY from RAPIDLED?My main barrier right now is money and it may take me some time to switch but it looks like LED would solve my issues.The time it takes for me to save up for the switch might work to my advantage because some of the spectrum ratios may be more refined by then.I'm doing a lot of reading but I'm a newb to all of this and any help would be appreciated.It would be great if their was a Sticky thread in the LED section just for helping people with DIY LED.

Yeah................they need a good slap on the fan leaves............your girls are gonna really impress some heads around here

Is it possible that 2 of these 56 watt panels for $500 could do the same job? Seems to good to be true. The inside measurement of my scrog screen is 2' x 4'.

Correction,after checking again it looks like I would need 3 of these.But still that's only 168 watts.

NO.........won't replace that much wattage or penetration you would get from those area51 panels.......they do use good leds, so It would take many Hans panels to make up for it and you would STILL lack the penetration due to the lense angles...........only advantage would be less heat from the remote driver and less wattage; your yields will be smaller too............can't have your cake and eat it too:P

They've come a long way, bud. So close now...

So i guess the real question is... What are your plans for the next grow? Lighting...strains....etc...?

ha........next round will be a comparison grow between 2?? (Hans may send another panel/ hasn't decided yet) hans panel vs indagrow 100......the strain choice maybe interesting for the RIU communitycould be one of our own breeders/stay tuned.......

Yeah T5 work great........but in my situation(summer sealed room, no ac and no air exchange) their is no other option than a low wattage led panel.......

In your situation and HEAT is a huge issue I would take a strong look at Rhinogrow panels..........you get the remote driver and great leds with mostly 80degree lenses(way better penetration than Hans) and a larger footprint..........you can haggle with them too for a better price/ made in america! yeah that's right newworldicon:P



DAY 94 from germ............1&2001.jpg002.jpg003.jpg004.jpg005.jpg006.jpg008.jpg..........scoped and #2 is right on track for my vaca(30-35%amber).....#1 not even close but it doesn't matter, she'll have the same fate and time as her sis............couple gnats are still flying around lol/ never got rid of them.............


007.jpg................56watt phase/ 54th day of bloom--longest auto grow ever/ 11-13/ be safe and happy growing

I feel ya Brother on pic #5, had the same exact feelings. Damn #2 is lookin Mighty Fantastic, is she about ready for the clippers?

^^^^^ That about sums up this grow!

Oh, riu breeder seeds... So cryptic. I'm intrigued. lol. As long as it isn't more subcool shit.

So whats the story with the panels? If hans gives you another one you'll do an all hans grow and if not you'll purchase an indagrow 100 and do a side comparison?

Cpt M: This is an indirect answer to your question. I think it's important to bring others up to speed on LED tech.

Slowly, we are learning that the 460-590 are important to highest quality, meaning RB alone never was the answer 100%. The majority of led manufactures focused on R/B, any other spectrums were hard to come by and very expensive, up until ~ 2 years ago. But it takes fixture mfgs that long to incorporate new tech due to things like inventory. Until they draw down their inventory they aren't releasing newer tech. And if they do, it is many times more expensive.

LED tech is a lot like computer chip tech- storage=white diode tech is doubling ~ 9 months, BUT, we don't see it commercially for several years, not so with DIY.

If you think of the sun in electrical terms it's Analog, whereas indoor lighting is like Digital. Sony introduced the SACD music format~ 10 years ago. It is the closest medium to this day to matching analog, but Sony priced its' use beyond main stream mfgs, let alone DIYers. The existing commercial digital formats will never reproduce analog 100%. For most people that missing ~ 10% doesn't matter, but in mmj? MMJ requires roughly 10-20% of 460-590nms, which act as a catalyst to the others.

Today, companies like CREE have introduced Neutral Whites which provides ALL the spectrums indoor gardens need in a single bulb in ample quantities.

A DIY led thread on another site: a guy uses a Kessil 350 but has built parallel runs of CREE NWs (~20w). These and just about anything you want is available as DIY solderless kits! On that site another has a DIY who started a grow where he mixed R + NW. He decided to remove all but 4 Rs (I forget which nm, but probably 660s) and is blown away by the vegging performance AND coverage. My idea is R (660) should be on a separate circuit/on off switch to be used from flower- harvest.

Rapidled has solderless kits using 5w CREES (nms buyer choice!), outputs range 60-120 watts. The 4.5 X 23 @ ~150w is $250 (covers ~ 20 X 30"), including tapped/drilled heat sink. They are made with better quality parts, use no fans (noise) with the BEST leds currently available

That will be fun to watch. consider me subbed!

Pet,thanks for taking the time to help a newb get a handle on this stuff. The weather is cooling off so heat in the cabinet is getting better. I'm probably going to DYI some LED fixtures but will do it this winter. As long as their ready for the spring when things heat up again. This will give me more time to learn which spectrum's are working best for others and research and design my own. I found a heat sink and connectors that looks like it would be good for designing with,easy to change out LED's and change layout without soldering.

On the issue of heat with my 8 lamp T5,it has dual ballast with 2 switch's. How much heat could I remove from my cabinet by rewiring it and moving the ballast's outside the cabinet? What percent of the heat do you think the ballast's put out compared to the lamps?

psuagro they llook good other that they are taking longer I really dont know how you could be so upset man 56watts and you are getting some nice looking buds. I am sure you will easily do better next time around but this isnt too shabby !!
