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.

That it will work on a Stil weedeater
Style: 9" 2T Cutting Blade
The edger connected to my Stil weed eater and worked great. I would recommend it to anyone.

Cut edges like a pro
Style: 9" 2T Cutting Blade
Better, much better than the OEM yellow and black brand. This has an all metal guard and the blade does not bind when it comes into contact with concrete. I have used it all summer for edging two commercial properties and my own lawn, it’s still turning and cutting with ease. Being all metal adds weight but the trade off over fragile plastic is worth the durability.

OK for light duty use only
Style: 9" 2T Cutting Blade
Not very strong or robust. Does fit my power head properly. Only recommend it for occasional, light duty use.

These work for the Worx trimmer WG928
Size: 16 Line Spools+4 Caps, Size: 16 Line Spools+4 Caps
Recently purchased the Work String trimmer and blower bundle. I found these and ordered them in hopes they were the right ones. They fit and work perfectly. Super easy to install. Pop out the old one and pop in the new. The string is pretty durable and thick. I love the idea of pre loaded spools. It got so annoying having to rewind the string on the spool every time I ran out. Price is fair and worth it. Highly recommend these if you have the same trimmer.
