What is the difference between T5, T8 and T12 lamps?​

Fluorescent lamps, or fluorescent linear tubes as they are also known, are categorized according to their wattage, shape and diameter. The "T" in T5 indicates the bulb is tubular shaped, while the "5" denotes that it is five eighths of an inch in diameter. The other common lamps are the larger T8 (eight eighths inch = 1") and T12 (twelve eights inch = 1½" tubes).

The T12 is an older generation fluorescent bulb that generates light through electromagnetic induction, which is considered less efficient method of creating light compared to that of newer electronic based circuits. Like the T5, the T8 tube creates light through advanced electronic circuits and are available in standard 2, 3, 4, and 5 foot lengths. However, what sets T5 fluorescent lights apart from T8 bulbs is their dramatic reduction in size. T5 lamps are 40% smaller than T8 fixtures, but are capable of containing just as much and sometimes more light in a smaller area. In other words, more T8 fixtures are needed to produced the same amount of light generated by significantly fewer high output T5 bulbs. Although the newest T5 lights generally cost more than T8 models, they are lower maintenance than other fluorescent bulbs. This combined with the T5 bulb's ability to provide more light (lumen) than the other bulbs means long-term cost savings on your commercial and residential projects.

I've been using HLG Rspec continuously for 7 years now. Have never measured intensity but they seem as bright as the day I first turned them on.
When these die I'll get more HLGs or something from @Grow Lights Australia

At a rough estimate of running 15 hours a day 365 days over 7 years it's about 38000 hours of use.
I can see them doing the 50000 they claim easily. Temperature conditions range from 12c in winter up to well over 35c in summer.

50000 hours is what diode makers claim the diode last until outputs gone down to 70-80% and 7 years is about what meanwells top end driver warranty, but only if you buy them from the correct dealer. A china light with meanwell hlg has whatever warranty the seller says, and generally not the same lifetime.

Growlights actually last quite bit less according to migros tests but without all details (is input current exactly the same as in the first measurement??) its hard to evaluate how valid this is. Still, i like migros "as is" testing- the ppfd/w rather than ppf/w seems a more valid measurement for growers.

 

[negative37dBA]

I have gotten over 4 years of 24/7/365 growing with my DIY LED. That's about 17k hours of use at 12/12. Still growing strong. Hearing people getting 38K is very nice!
Peace, negative.

When you diy its easy to build in a long life by overspecing heatsinks and running diodes soft. Weve had similar usage, though not 24/7, on our lower end gear some have had dim rows but never nothing on higher end components including alibabla lm301bs with no heatsink at currents nominal or just over.

One thing I've seen lately is people buying say 1000w leds and never running them more than 70% to 80% because that will make the diodes last longer because they are not running as hot or as much watts through them.

My HLGs that I mentioned have the really fiddley adjustment on a screw thread that's inside the MeanWell Driver so I've ran them at 100% their entire life and just adjusted hight so that's even more impressive I think.

One question I've actually asked but haven't seen to get an answer for is when the lights do start to drop in intensity is that from the diodes degrading or the driver degrading? As if it's one or the other I could easily replace them for much cheaper than buying a new light.
Anyone know which goes first or how to check if one is performing poorly and the other is fine?

Diode decay is real. Driver, i wouldnt know never tested it. I assume so. But drivers temd to fail completely, not turn on. Diodes tend to go dimmer and dimmer or even burn out, but the leds dont fail all at the same time.
For meanwell drivers theres an awesome report section on their web with loads of info on the drivers actual real spec, rather data sheet nrs these are measured values and closest to what you will get. Meanwell tend to over spec their drivers, more output than whats supposed to be.

I recently lost a red in a 288 board from KB. It might be 5yo though. It was taken out of service briefly, as I would rather swap the boards at 3 or 4 years. I then needed it again though.
A meanwell should last about 7 years iirc. The Samsung diodes could do with changing by 5 years, to keep up the efficiency. So logically the board wants changing at about half the drivers expect lifetime. Which is installation and usage dependent. Likewise with the LEDs. You can never be certain, but average working times are all we can expect.

Total outage of an LED usually comes from thermal cycling, causing physical damage. It's a common failure mode. Otherwise they will shift colour and get dimmer.


Edit: My failed QB revealed itself as my fault. It didn't like watering. More in a few pages..

Humidity and burning sulfur also does a nice number on them, we seen more boards grow dodgy in our veg space. Sealed boards should be better as long as the temps are similar.
Thermal cycling also seems to affect the actual pcb - my mate did a bare board light on very low watts and had a few boards fail completely; not burnt diodes but just board stopped working.

I’m just (or was) about to pull the trigger on an hlg and wondering if your hlg is an older model or new ones have a fiddly adjustment as well? Id rather have something easier to adjust.

A diy sounds like a fun project.

HLG the light brand, to my best knowledge have an external dimmer.
From porkys description id say hes talking about Meanwell HLG series driver which come in with 3 different versions of dimming according to suffix in model nr: A version- internal dimming, both current and voltage (voltage dimming is very practical imo opinion, you can reach around 10% higher voltage than normal spec) but you have to push a screw driver into a hole of the driver to adjust in a not always precise way, B-version 1-10V 3 in one resistive dimming including PWM and AB version, which has both internal and external but seems to be missing voltage adjustment on most versions.
If you throw up a thread on your DIY project im always happy to help, just tag me

Yeah as far as I know all the new HLGs have external dimming.

I've got lights from spider farmer, viparspectra, mars, kingbrite and cultiana i've had good results with them all tbf.

The spider farmer se is my favourite spec/build light (dimmer aside its pish) but the light feels solid and has lm301s and a meanwell driver.

Sometimes when an LED or row goes out, you can poke your finger at them, making them come back on.
IIRC my LEDs will of lost about 15%, as daily switching kills them. It's interesting to hear it's your veg space finishing them off. Where they really should last many years, if it's 24/7

Liked it enough to buy the KS5000, which is finishing its first run.

I think its the combo of environment with high rh, occasional sulfur and being the retirement home of our old boards. Also, it runs my old fave the fotop board, (900x280mm) without heatsinks - even if its low watts and doesnt get hot there seems to be a need to have atleast something on the back, even if its just for structural support. I also suspect my buddies it may have been how they were hung previously, just from the ends with possible sagging in the middle. Tbh those boards were cheap AF and 561C of Alibubbers origin, who knows what kinda reject diodes they are.
Its way overdue for a renewal, id like to try somethings in the future but right now im focused on getting those last decimal points on flowering.

The datasheet and reality doesnt always line up, especially with alibaba or china brands. Reality always trumps out what should happen
