To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Arrived quickly, nothing was broken good replacement bulbs but some of them went dim and basically useless after only about 6 months. The lumen output was down to ridiculous level. The other brands purchased around the same time were still putting out plenty of lumens.
I bought these as a replacement for some plant growing tube lights. I needed 4 foot long bulbs (ie. 48 inches). Although the title of this product says "LightWise LWF54T5HO865 8pack 4 FT 6500K T5 HO Fluorescent Grow Light Bulbs (8, 6500k - Blue - Veg)", they are NOT 48 INCHES LONG!
They are actually about 46 and some inches long. They should be called "approximately 46 inch bulbs" in their title.
I could not find any were in the posting the actual distance of the pins; so I thought I would take a chance even though others had a problem with this fitting their light fixtures. They did not fit mine either. The distance between the pins center to center is 3/16 of an inch. I only rated the product a 3 star because the seller has not posted the distance between the pins even though many people have had a problem with this. I do not know how the lights work because they would not fit my fixtures.
I'm changing my review. These lights do not last very long. I have bulbs from other companies that out last two or three of these bulbs. It seems like every time I turn around I'm replacing one because it's burnout. It is not my equipment because I have other brands right next to these. I have changed the location of the balls around in the light to see if the light was bad itself and it is not. The problem is the bulbs
I highly recommend swapping out your fluorescent bulbs every year or every three grows. I used them for the vegetable cycle and are on for 18 hours a day. You can see a drastic improvement in the plants as soon as you swap out the old ones with the new.
The eight bulbs I ordered were well packaged and arrived safely. (As they were inside a thick cardboard tube, I would not expect to find any breakage.). I own a couple different brands of fixtures, mostly Sun Blaster. And the bulbs fit the fixtures, no problem. The greater brightness that comes with a new tube was apparent. I noticed that a lot of the bulbs I replaced were the same bland as these. And those 8 or 9 bulbs had been in use for about a year with no problems Very pleased..
i am always worried when ordering light bulbs online, but the price on these was cheap enough that it was worth risking it over buying a brick and mortor store. the packaging was great - in a really heavy duty round tube - and they all arrived intact. i haven't used all of them yet, but so far, all of them have worked and are still going strong. will definitely get these again in the future
