Lightspeed CMH 630W 3100K Double Jacketed LampSwitching from a 1000 watt high pressure sodium or metal halide system to a Lightspeed 630W ceramic metal halide system will increase the growth, health, and yield of your plants and will lower your energy costs by up to 70%. The wide spectrum of our Lightspeed CMH bulbs allows either the 3100k or 4200k to be used from the vegetative phase straight through to flowering, or for maximum growth and yield begin with the 4200k bulb for vegetative and then
Switching from a 1000 watt high pressure sodium or metal halide system to a Lightspeed 630W ceramic metal halide system will increase the growth, health, and yield of your plants and will lower your energy costs by up to 70%. The wide spectrum of our Lightspeed CMH bulbs allows either the 3100k or 4200k to be used from the vegetative phase straight through to flowering, or for maximum growth and yield begin with the 4200k bulb for vegetative and then switch to 3100k for the flowering phase.The lower wattage of our 630W CMH bulb versus the standard 1000W HID bulb translates to less heat being expelled from the bulb and the ability to place the grow fixture closer to the canopy, increasing light intensity and canopy penetration. This double glass jacketed lamp features a double ended lamp base and is rated for open fixture use. The ultra-efficient ceramic metal halide system can do the same job as MH and HPS with better results, using less power and emitting less heat. Lightspeed 630W ceramic metal halide bulbs pair well with any double ended 630W system, like our Lightspeed CMH DE 630W System or the Lightspeed Digital CMH 630W Ballast.

Cute and comfortable.
My son loves them. He's only worn them three times so I can't say yet how they hold up. But he's happy. My only wish is that the laces were a little longer so that he could have an easier time tying them. They do also come with an extra pair of turquoise laces.

saucony for life, kidz.
Color: Navy/Silver/Pink, Size: 7 Big Kid, Color: Navy/Silver/Pink, Size: 7 Big Kid
… why I appreciate being an adult female with average-sized feet, Especially considering kids’ shoes are always way cooler!
The sizing is a bit wonky, I’m normally a women’s 8, EU 39 which were my last saucony’s ,
These were exchanged after buying the “big kid 7” (too big),
after replacing w the 6.5 (38.5 EU) I still wondered about sizing down more but I think they’re good, they just fit differently than my previous ones… also I replaced the very long blue laces (48”) with shorter white ones (40”), and now I’m keeping and loving the shoes!

Runs Narrow
Color: Blue/White, Size: 1 Big Kid
They seem to run quite narrow, for my son who wears a medium comfortably. The New Balance fit much better.

Comfortable boy shoes
Size: 4 Wide Big Kid, Color: Black/White
My son’s favorite sneakers. I think this is a fourth pair we ordered as he grows. Lightweight but mostly wide enough to be comfortable. I wouldn’t buy them for a full price but they are often in sale and then it’s great value for my money.
