DOES ANY ONE KNOW IF LED LIGHTS CAN BE REPLACED WHEN BLOWN OUT?x

IM GETTING AN LED LIGHT AT SOME POINT, TO COMPARE HOW PLANTS GROW WITH IT, SO DO YOU GUYS KNOW IF LED LIGHT BULBS CAN BE REPLACED IF BLOWN OUT, OR WILL A WHOLE NEW SYSTEM HAVE TO BE BOUGHT.x

Why do your own experiments when plenty have already been done.

This is my favorite comparison video. http://www.youtube.com/watch?v=_CtROw3uiVg

LED's are supposed to last years and years and years. You shouldn't have to replace any lights. But if you have some soldering skills you should be fine.

You'll probably just need to solder a new one in unless they did some cool trick like cover everything with epoxy, but I doubt it since that would cause problems with cooling. Shouldn't be that big of deal.

Most LEDs tend to last about 10,000 hours before they even show 2% decline in brightness... that's about 14 months. At 50,000 hours, light output is about 70%. It's worth getting a second light and just shining both on your plants.

As long as the fixture keeps the LEDs cool (higher output LEDs can get very hot), it can easily last several years. Most LED light manufacturers solder their LEDs into place, though I can't speak for that specific manufacturer. That may be a question for the retailer or manufacturer.

Best of luck on your grow! :leaf:

Regular LED's have 2 wire leads coming out of them that are soldered. You have to unsolder them to get them loose and resolder a new one on. You need a soldering iron and solder. You may need some type of desoldering tool if you aren't that good at soldering also.

Soldering is a process in which two or more metal items are joined together by melting and flowing a filler metal into the joint, the filler metal having a relatively low melting point. Soft soldering is characterized by the melting point of the filler metal, which is below 400 °C (752 °F).[1] The filler metal used in the process is called solder.

Look up soldering on the web if you have no idea what it is.

Soldering is how electronic components are attached to a circuit board or other wiring to attach the components together and make them work...

Aw, you beat me to it, la9. I like that you included a quote from the link I provided. Gotta love wikipedia.

I should also mention... the 14 months =10,000 hours is based on 24 hours of light. You'll probably get much more life out of it, considering you won't be using it 24/7, at least not during flowering.

but i dont think its worth it if its not easy to change the led buibs

I disagree entirely...

Let's say you use the lights an average of 15 hours a day. That means, after almost 2 full years, the brightness would still be at 98%. In that time, you would have spent $280-$360 on HID bulbs alone. Also during those two years, you saved over $1100 on your power bill (assuming $0.15/kWh). The LED light has now paid for itself, and it still operates at 98%.

After about 9.5 years, the light will be operating at about 70%. It still uses 25% of the power an HID system would cost, so producing 70% of the light isn't a big deal... get a new light in 5 years if you want, but keep the old one and use them alongside each other.

Now, does it sound worth the money?

putting it that way it does sound worth it.
but on the other hand y dont more people LED if its better then HID lights?

Your forgetting something here. What is the difference in yield between HID and LED. If the difference in yield was not so great I would be all for LED. But in all the videos I have seen and threads I have read about, LED produces much less potent and very little quantity compared to HID.

True nothing beats HID at this point in time. If you haven't made up your mind yet definitely go HPS to flower. I'd say go with flourescent to veg with but that is my opinion, don't want to get another big name calling debate started.

I believe eventually LED will rival or even surpass HID, but for the time being HID is the way to go.

However if you wish to pursue this course of action please do post a grow log and link us to it. I would be very interested to see what kind of results you get.

If your not sure if you want a 400 or 600 get the 600. You'll be glad you did. Who among us doesn't upgrade all the time. Check into an air cooled hood there so worth it.The money you'll pay isn't all that much more.

If u only knew how much im taking into consideration
