Lighting LEDs direct from china

[lazylathe]

You'll probably see your pics used for marketing... :joint:

Try and get a free light in exchange of a diary or hi-res pictures!!

Sounds like a good idea!!
Free light for a journal!
Thanks!

So I bought one of these instead: http://www.ebay.com/itm/135w-UFO-LE...556?pt=LH_DefaultDomain_0&hash=item416c8d4bd4

This might be the same one, but $7 cheaper: http://www.ebay.com/itm/Pro-135W-8B...375?pt=LH_DefaultDomain_0&hash=item337f8d3ba7

Differences: The angles are 90 and 120, but I'm using a SCROG, so it won't matter. They also don't have the replaceable/upgradeable light modules, which would have been nice, but probably won't affect me, or the X2 optic lens, which I'm not sure what it does. $103 total with fast shipping is extremely cheap, though. I think it's worth the lower quality, at least depending on whether you're doing something that won't need a lot of penetration. I've seen them go for as low as $90.

I'm going to do a grow log with these and will link you guys if I remember.

Light came Friday around 2PM (California).

Seems to be the same as this, maybe with different LEDs: http://www.ebay.co.uk/itm/135W-LED-...arden_PlantsSeedsBulbs_JN&hash=item336e69ac95

It has the same hangers, which I don't like because they're too long and I'm going to use rope ratchets when they arrive (Bought from the same seller for a low price. $4 total for a pair seems to be the median.), but I just looped the carabiner over and under until it was short enough.

Seems to be what they say it is. I like it, but time will tell how it performs. It produces very little heat. My grow space is only about 7 cubic feet and made with reflectix and it hardly raises the temperature, it seems to stay around 73F. Only thing I don't like is that it's too loud.

According to my Smart Tools app: https://play.google.com/store/apps/details?id=kr.sira.sound&hl=en

The decibels are 27 from a few feet away in the same room. Maybe you could play a youtube video of a fan blowing and raise the volume until the app reads 27db to get an idea of the noise level. Here's one you could use: http://www.youtube.com/watch?v=yOtGBwMSjng

It's certainly not inline fan loud, but I definitely wouldn't want to be on the computer or sleeping in the same room as it, and it isn't suitable for a stealth grow. I may have particularly sensitive hearing, though. I've never listened to loud music, so I haven't suffered as much hearing loss as the average person, and I've always been easily annoyed by noise.

Here are the internals. Only 3 phillips head screws, easy to disassemble and put back into place.

This is the fan: http://fan-cooling.com/productshow.asp?id=72

Seems to be a standard 120mm DC PC fan. Looks pretty cheap, no wonder it's noisy. Easy to swap out. I might need a 3 pin to 2 pin adapter, though.

Anyone have a recommendation for a replacement? Something cost effective.

Anything I should know about replacing the fan? The page doesn't have any info, so I don't know how many CFM it is.

Ah, about noise. They have lights now without fans, just huge heatsinks: http://led-star.en.alibaba.com/prod...ge_used_greenhouse_used_grow_lights_sale.html

Found here, this thread is insanely big. It will take a while to skim through it: http://www.rollitup.org/led-other-lighting/486179-led-companies-w-links-64.html

LEDs will eventually be perfect. Efficiency keeps increasing, price keeps dropping, and they can be silent.

Hey lads!

new to this forum and kind of bumped into it when i searched or should i say, tryed to search up some info on some hollandstar 300w 6band lights does anyone of u have any experience with them? not sure if i should go for those 120 w and maby expand later on.

Planing to build my self a hydroponic sys for 4-6 plants at start.

Dont have too much money to trow around atm :|

sorry about the bad language btw

YO Toxicated! Welcome to AFN!
Those lights you have chosen are ok but there is better out there mate.
Panel type LED's are now being phased out and replace by the new modular series, im in the uk but have been testing LED's for some time now and use modular which are outstanding, check out my albums in my pofile.
The more wattage, the better aswell plus getting a good long warranty on them is a must.
This one doesnt go into what spectums it uses aswell and thats really important.

 

[Toxicated]

Thanks Mate

Aye, I`ll wait a bit with them lights, and get some good ones with new technology instead, I`m not in a hurry anyways. Will go a couple of months before i start, need a new apartment first. Thought of just starting to get some equipment

Cheers again, for stopping my rush!

[Nemesis]

I myself am doing two grow threads with LEDs, one is similar to BSLEDs but its got bespoken internals, customised spectrum etc..
Check out my albums for pics.
Anyhoo my results are excellent and im only using the 4 Lense (240W) one.
Will be testing the new 300W Helios range aswell soon.

Testing is the proof my friend so get some beans under that bad boy! lol
