Grow Light Canada Listed Performance speaks louder than words.This Grow Light Ballast simply outperforms the rest. Why buy a magnetic ballast from a Hydroponics store chain that will consume more energy and give you less light? This ballast puts out 50% more than the competition's magnetic ballasts! Numbers don't lie.
Lighting is the most important factor for gardening and this high-quality FCC tested. This ballast will provide great lighting at any dimmable setting. The silent, cool running, and fast starting ballast is packed with safety features to ensure great longevity. If there are any circuit problems (that can be caused by a faulty bulb or even wire), the ballast will shut off. The ballast is resin en coated to ensure that the surrounding environment will not cause any damage. This ballast is completely switchable and will work with MH and HPS bulbs. Next, to genetics, lighting is the most important factor for indoor gardening. Grow Lights Canada is proud to offer the latest advance in ballast technology. These ballasts offer a glimpse of the future of HID lighting control systems. They offer an improved design and increased efficiency while delivering the best performance in the industry. Lab tests have shown that these ballasts use up to 30% less electricity and are up to 30% brighter than traditional magnetic ballasts. Tested against the 3 top-selling brands in today's marketplace, Grow Lights Canada ballasts outperform them all in terms of power consumption and light output.
*Do Not use any ballasts with flip boxes, these cause power leakage into the ballast that will cause them to fail

6 in Cool Tube

This 6" Cool Tube Reflector can be mounted vertically or horizontally with or without the insert and wing. It is 24" long and the wings can be adjusted to perfectly fit the pattern you are looking for. This is one of the longest Sun Tubes units on the market. When comparing competitors' units, make sure to check the length, many 19" units are being sold that use cheaper components and glass.
This reflector was manufactured using polished and textured German Aluminium which has a reflectivity rating of 95%. The tempered glass tube is very durable and there are twin 8" aluminum flanges on both sides of the glass tube. This allows you to connect duct work to vent air from outside your grow, pass the air over the bulb, and vent the air back outside your grow room. Only the heated air from the bulb is removed. Perfect for grow rooms using CO2. and pull cool air over the bulb. It greatly reduces the heat going to your growth. The reflector comes with our industrial 15' lamp cord and socket which is compatible with all size HPS/MH bulbs. The connector is the standard Universal Type, compatible with most major ballast brands.

Excellent plugs, superb performance
Exactly as described at a decent price. I've found over my decades of doing my own tune ups, the one thing you can't skimp on when tuning up your vehicle, plugs and its shows if you do. Out of the box, all 4 were gapped correctly. Ease of installation depends on your vehicle and ones mechanical ability with PATIENCE. 100% compatible with my vehicle, be sure to match you numbers. Overall 5 stars for performance and price.

💯% Authentic NGK Made in Japan.
Got these for my 2016 Subaru Crosstrek. You can't go wrong with NGK, these are 💯% AUTHENTIC, and made in Japan, unlike other NGK plugs that may be sold by other sellers which could be made in Thailand. The Subaru Crosstrek is running like a brand new vehicle after I put these puppies in it.

Worked like a charm
Worked like a charm. The box and packaging were adequate from keeping the gaps of the plugs from being squished.
