Recently I purchased a Blockbuster 6 reflector. Actually I bought 2 of these air cooled reflectors for my grow closet and so I thought I would write a review on the Blockbuster 6.
I had been using a wing type of reflector in my 6 x 3 grow space. Light was good in the middle but fell off at the ends and penetration was not all it could be either. Also I was having a problem keeping temps down with an uncooled 1000w HPS.
Because my grow closet is twice as long as it is wide I was spreading a single bulb too thin for the space. So I decided to go with 2 600 watters instead and I started looking for a good air cooled reflector. I read a lot of reviews and I know there are a lot of differing opinions and what the best grow hood is.
A lot of growers like the Magnum and Raptor reflectors but these are really too big to fit in my room. Plus they are heavy and still use only one bulb. Uniform lower light levels were not what I was after. I wanted a reflector that focused the light downward and gave me good penetration into the canopy.
I happened to stumble upon a reflector test done by Greners while doing my research and you can see their chart below.

Now I am not saying this is the be all reflector test but it’s what I had to work with and I have yet to come across anything better or more inclusive. You will note though that the top spot went to the Luxor. Also the most expensive, well they are in the business of selling reflectors, so the results could be skewed a bit.
Air Cooled Hood Comparison
The Luxor has a vertical bulb and I know some growers really like vertical grows but it seems by putting it deep inside a reflector you lose the advantage of an open vertical bulb grow. Besides the high price tag this sucker is almost 20 inches tall which means by the time you’re done hanging it you have wasted a lot of vertical grow space.
The Blockbuster 6 reflector comes in right below it though and at almost half the price. If you look at the chart it also outperformed both the Raptor and the Magnum. The Radiant also performed very well and if you want a good bargain reflector this is a good choice too. I decided to go with the Blockbuster 6 reflector because I felt it was a bit wider and would have a better footprint inside my grow closet.
I have to say I have had no regrets buying the Blockbuster hood. There were a few anxious moments where I was afraid both reflectors wouldn’t fit. I don’t know what I was thinking when I ordered them because when I saw UPS carrying them up to my apartment I suddenly realized how large they were.
I bought my reflector on Amazon because I got a better price and shipping was free. But: “The dimensions are 25.5″ width and length x 9.5” tall.
I wound up mounting them with both the bulbs facing the center of my grow. I think this compensates a bit for the improper orientation as the back end gives off less light. They work really well but for a while I was feeling like a complete idiot.
Here is a rundown on the Blockbuster reflector features
- Top of the line reflector from Sunlight Supply Square footprint
- Gives you a very uniform and intense light pattern.
- 6″ air cooled hood
- Inside lined with 95% reflective European aluminum.
- Seals very tight with neoprene gaskets.
- Hinged glass is easy to remove and has side safety cable.
- Comes prewired and uses common style plug.
- 15′ long lamp cord.
- Housing is galvanized steel with Dupont powder coat finish.
- Includes hanging hooks
I would have to say this is a very well made reflector it is solid and well designed and not some cheapo Chinese import.
The Blockbuster reflector seals very well. It runs extremely cool. The glass itself only gets slightly warm so you can get this reflector really close to your plants. The housing is actually cool to the touch even right above the bulb. You can’t even tell there is a grow light inside that’s on. My temperatures now are about 82 degrees with lights on which is perfect whereas before it would climb into the 90s.
The Blockbuster hood has a cable on the side to keep the glass panel from falling down on your plants when you open it up. You can remove this and easily remove the whole glass frame should you want to as the back hinges hang on tabs making this easy to do.

Blockbuster 6 Video
This is an older video and doesn’t show the side cable that keeps the glass from dropping too far when you open it. There is plenty of room to get inside to change a bulb or clean the glass so I really cant see any reason to remove the glass anyway.
Nothing is perfect and that includes the Blockbuster 6. I found it a bit difficult to get the thumbscrews on top to line up with the holes on the bottom. Of course I am working in a cramped space and it would undoubtedly be easier to do if I had more room. The only other thing about this hood is that I felt the hinges should be made out of thicker material.
If you are looking for a great air cooled reflector I would definitely recommend the Blockbuster 6 Reflector to you and you can get it here.
