I'm Brian, the founder of Transcend.

Each light is 19 pounds and is about 10"x8".

There are two reasons the light is the size that it is. First temperature. We have a passive heat sink with fins and a plastic remote phosphor sheet. Both have to stay relatively cool and more surface area makes this possible.

Its funny, the first fixture we built and sampled to growers was about 25x smaller. We used an active heat sink and a glass phosphor sheet. A common complaint was "why is this so small?" I want my lights to be "big and strong". We took this feedback and decided to move to passive design.

Our original logic was that smaller is better, especially in a greenhouse. The most efficient light is one that is off and the less shading of sunlight the better.

Thanks for coming here to reply to comments!

I think small lights could be a really good market for you, for all the urbanites like me, living in condos. Make a tiny kit that can grow herbs or lettuce at an accelerated rate using little power because of LEDs, and I'd buy it in a second.

As it stands, I think a 1m strand of TL-RL20 will be a purchase for me soon, and I'll build the kit myself.
