These are great replacement LED lights for hi hat fixtures. They work great, look great and dim very nicely. I reduced the rating from 5 to 4 because I ordered 6 of these and I received 5 100 watt units and one 120 watt unit. The 120 watt unit is to tall to fit in my high hat fixtures and by the time I got them installed my return privilege had expired

The label on the box states that the bulb is suitable as a 40 watt replacement. That couldn't be more wrong. The bulbs are more like 4 watts not 40 watts. Very disappointed and will never buy again. Waste of money.

Not even close to the advertised 120w.  Light pulls 3.6 amps at 13.2 volts.  Total Wattage is 47.5.  Still, quite bright, but not as advertised.

I purchased based on 2000 hr. rating.  My desk lamp came with 20w bulbs but I replaced with these 10w bulbs. I ordered 1 extra thank goodness. In less than 2 weeks of normal night time usage one has burned out. There were a lot of  less expensive bulbs listed for as much as 70% less but without a norma life rating. I am now wondering if  I should have purchased the less expensive bulbs

Ordered the 400W unit and received the 520W.  Score!  Nice big fan, but no indicator light.  Unit arrived on time and is working flawlessly.  Definitely a good budget buy.

This states that it is 300W Replacement.  I take issue with that statement.  I put the light up and if I had a small area, it might would have been OK.  I have a fairly large area where I had been using a 100 Watt Metal Halide fixture. It seemed very dim in comparison to what I had been using.  The LED fixture is rated at 4,000 Lumens whereas most metal halide bulbs are rated at 8,500 to 9,000 lumens for a 100 watt or equivalent bulb.  The LED fixture states that it uses 38 watts.  The Metal Halide will use 100 watts or more, but if it is for security, I feel it is worth the extra cost.  I did return the LED fixture, ordered a new Metal Halide bulb from Amazon.  Amazon is great when you need to return an item and that is the reason, they are the only company I will order from.

I ordered the six watt buy three special but only received one six watt. The other two were 4 watt. Very poor quality control. Too much hassle on a I need it now to install item. The lights are bright it is not what I payed for.

Michelle from the company has looked into the shipping error and has refunded the amount difference, so once again a happy camper. Again, thank you Michelle S. for stepping forward to resolve my issue.

Bought a 450. Seemed legit so got two 1000 watters. It's been a little over a month and two rows of leds went out on the 1000 watt. One row on the 450 and a single led on the other 1000 watt.  For what I spent on this I could have purchased a good platinum series.

I installed 10  45 watt units on my home in different deticated locations . This one  60 watt makes me wish I had seen this on first. I intend to buy 5 more in the near future

Received yesterday and was pleased with performance. Initially had a 60 watt bulb in receptacle. Now have 4 bulbs with a total of 48 watts and so much more light in my attic. Swivel is easy to adjust.

So far I really like the bulbs and give the bulbs themselves 5 stars. Three of these bulbs in one fixture seem to compare equally to four standard florescent bulbs in another fixture I am waiting on more bulbs for. The reason for only three bulbs is because I damaged one when rewiring my fixture. I should have read another reviewers comments closer when he said:

If you're keeping your ballast, don't worry about this. However, if you want to eliminate the hum and decrease power consumption, you should use the bulbs directly -- with the right instructions, rewiring is easy. These bulbs are "dual end" power, which means that one side should receive the live (black) wire and one should receive the neutral (white) wire. The two pins on each side are internally connected; you only need to feed the wire to one side of the socket. Having figured out the right instructions, I rewired the second light fixture in less than 10 minutes.

What really would have helped would have been if Hyperikon would have included only the instructions for the bulbs I received. Instead I received instructions for both single and dual ended power wiring. The instructions for both could also be written a little better.  One should not have to go back to the Amazon web site and read peoples reviews to figure out how to use a product.

Also, I left packaging feedback for this as well. I hate waste and was OK with these shipping in their original box, but they need to tape the ends closed on the box. I received my package from FedEx with the contents hanging a few inches out of the end of the box and both ends of the box were hanging open. I was happy to see all four bulbs still in the custom foam packaging though. Hope my next order shows up intact.

Update: It turns out I did not damage the bulb I thought I did. I received 5 new bulbs with the same shipping issue with the box of four but the fifth one came in well packed in an Amazon box. I measured the power draw of my four T8 bulb fixture at 180 watts, bulbs and ballast. I then just replaced the bulbs to get a power reading, but only three bulbs would light. I believe my ballast might have been the issue there. Next I took out the ballasts, rewired the fixture and double checked things. Powered on the light and all the bulbs came on. Then, about three seconds later, the bulbs went dark one by one. I switched the power off and back on and nothing, I walked over under the fixture and three of the bulbs popped and started to smoke inside the tubes. I was a bit upset by this. I called Hyperikon after receiving emails from them after each purchase. The person I talked to was very nice, told me there was nothing I could have done to cause the bulbs to fail and they shipped me 6 new bulbs. Hyperikon has very good customer service. I do worry they have some kind of problem they are working out with the bulbs. I do know that some devices auto-range to the supply voltage, and I kind of wonder if installing them in the fixture with a ballast first and then removing the ballast caused the problem. The first bulb that failed on me I remember trying by itself in the first fixture as well before removing the ballasts in it. At this time though my two fixtures are working will, with more light output than I had before and drawing only ~72 watts (measured) per fixture.

Beware some folks are selling this as a 150 Watt supply, labeled as 150 watts but really just a 130 Watt brick.  Deceptive and illegal mismarking of product.

It was advertised as being able to handle 1500 watts of power for CFL or compact florescense lamps but when I got it and read the instructions it would only handle about 150 watts.

It says 400W but don't be fooled its more like 360 watts. Misleading packaging makes for consumer mistakes. Which makes for a bad experience and a complete waste of time. I'm sure it works fine for that power range . I just thought I would be getting a power supply that was 400 watts not 400W.

I have a 42" 400w and it's not bright like it should be... so I sent it back and got a new one thinkin it was something internal and hooked it all up again and it's the same results idk what is goin on with it
