I agree with THG.

Did it both ways and I like the way the all 6500's grew better in veg. (shorter, stouter.)

I bought the PLL-55 fixture and tubes--they are a 2' double tube that emits 5000 lumens. Here they are:

I have the same set up.

But, now I get my tubes from xxx.atlantalightbulbs.com

Same price as HTG, but they last longer and are much brighter in a side by side. To be fair, the HTG bulbs were several months old.

The brand is EIKO.

I ordered & received a box of 4' t5 HO bulbs that are a 10k kelvin. I am usualy running 6500 K in my T5's during veg. I have never seen these 10,000 Kelvin bulbs before? What gives?

I am posting this here in case someone else shopping for a 8 bulb 4' T5 comes to this thread doing a T5 search.

I had my first less than great experience with HTG Supply when I recently ordered the 8 bulb SLIMSTAR model. Bad workmanship. While I was waiting on HTG to open up Monday, I found that Amazon has a vendor who offers a Hydrofarms 8 bulb 4' T5 for ten dollars less ($204 plus FREE shipping for a total savings of approx. $35) that's a lot better quality and comes with a 5 year warranty. I planned on returning the poor quality HTG Slimstar but HTG offered to replace it with their Growbrite model that sells for $270. The warranty is not as good but it looks to be the same design as Hydrofarms T5. I've always been pleased with HTG so I went along with them on this one. But I'd suggest looking elsewhere for a 8 bulb T5. HTG doesn't offer the best price or quality or warranty on the 8 bulb model.

It is important to note that T5s usually require new fixtures and cannot be easily retrofitted into existing T8 or T12 systems.However, using fixtures specifically designed for T5 lamps optimizes performance and prevents the misapplication of other types of lamps – a common problem with T8 systems. Compared to metal-halide systems, T5s offer better lighting quality due to a higher color-rendering index, better light distribution, and lumen maintenance.
