DragonLight120W Commercial Grade Corn LED Light Bulb(400 Watt Metal Halide/HID/HPS Replacement) E26/E39 Large Mogul Base LED Lamp 5000K Daylight 14,400LM for High Bay Area Lighting

I converted a 100w sodium HID with this. To do a correct replacement, you should remove the existing ballast and capacitor from the HID. This is brighter than sodium bulb, it is instant on, it is a warmer color temperature, and there is no noticable flicker. The only thing to pay attention to is the length/size of this-it is massive.If anything goes wrong, I'll update this review.

We have a large garage (1500 sq ft) and my husband was always complaining about enough light even though he had 300W incandescent bulbs. I bought this LED bulb and he loves it. It puts out 14000 lumens and is warm white, not that ugly blue LED. I bought two more and the whole garage is lit up. So instead of 1200 W, he is only using 400 W and getting more light. The bulb was pretty pricey but it's guaranteed for five years. There is a warranty card in the box which you fill out and send a picture to the supplier. They responded so I know they received it. This is WAY better than most suppliers that say there is a warranty.

I was surprised at how compact this bulb is when I opened the Amazon box. However, I was blown away by the brightness once I flipped the switch. I have a 12yd basement archery range that my kids and I use regularly and have three of these bulbs illuminating the length of it. The light output is great and the warm white color makes it a bit easier on the eyes than a harsh blue-white daylight type bulb.The bulb has a small internal fan that keeps it cool during use and I can feel warm air being pulled out from underneath. After using these bulbs for about a month, I can hear the fan making what sounds like a harsher noise than when I first installed it. So far, the fans and bulbs are working just fine, but I think the weak link will be the fans. If and when they do die, the bulb will have no way to keep cool and likely fail from overheating. I am hoping to be able to find a way to take apart the bulb and replace the fan should that happen. So far, I am giving 4 stars for longevity, since I haven't been using it long enough, but the fan is making me a tad suspicious. I will update this review once I have more time using it.

I have been working with Dragon Light via email since I installed my bulb into a photosensor fixture. The bulb failed after a few minutes in the fixture. I emailed Dragon and explained the situation and they resent me another bulb without cost. They kept in contact with me until receipt of the bulb and afterwards until I "tested" the bulb. I first tested the bulb in a standard socket and used it for more than an hour without any problems whatsoever--extremely bright. I was very hesitant to "test" it in the "photosensor" fixture again as I highly suspected that it would fail again. And on que it did fail within a few minutes. I provided the results of this "testing" to Dragon and they did state they would revise their notice regarding "not to use with ballast fixtures" to include "photosensor fixtures". Now, I do not know if my fixture also had a ballast (not sure?), but the first time I wanted to try it out on that light fixture I had my doubts that it would work--and it failed. Anyway, to keep it short--I appreciate that Dragon worked with me on this. GOD bless.

This light doesn't kid around about its equivalency, it really is a 400 watt incandescent, may even a little underrated. As a videographer I can really appreciate the high quality LED diodes, giving off a much more natural look than other led bulbs I've used. It is not silent, it has a small fan to keep the LEDs cool. Unfortunately that fan on my original bulb started to make a loud noise when it would first be turned on. The sound was the fan seizing/grinding but it would only last 1-3 minutes, then it would stop and you'd faintly hear the normal fan again. It's like it reset and fixed itself. Either way that was a bit annoying for my little garage, so I contacted the Dragon light and they immediately sent out a replacement! I almost felt bad, because the bulb never stopped working. I was just being picky, there WARRANTEE IS AMAZING!!

Work great

This product is advertised as a replacement for a 400 watt HID bulb. It does not come close to matching the brightness of a 400 watt metal halide bulb. Installed 21 bulbs in existing metal halide fixtures. The indoor arena that was well lighted is now dingy. I had tried a saucer light in one place before using the Dragon Light and now wish that I had used the saucer lights. Installed the saucer lights in a different barn and have a brightly lit area at the same cost without the substantial work to remove ballasts and rewire the fixtures.Other reviewers have commented on the poor quality adapters for the base of the light. I broke the first one. The aluminum adapter was the thickness of a beer can. I replaced it with a much heavier adapter purchased from a local hardware store.One of the lights never worked. I would have sent it back on the guarantee but the only way to activate it was to take a picture of the paper work on my cell phone and send it to China. I do not share my phone information and would have never bought the lights if I had known that this a condition of the guarantee.

Was a great light for the first year or so. Then only one side of the light would work intermittently and I believe it was overheating. Today it finally stopped working altogether after about 3 years.

I used this to replace a burnt 175w mercury R39 (mogul) it’s about as bright 7700 lumens for a mercury. The Color temperature is decent obviously more white but am very happy with it

Last long time compared to regular bulbs

Wir haben jetzt 4 im Einsatz, bislang alles in Ordnung. Ich höre den Lüfter nicht. In einem Friseur Salon ist aber auch immer eine gewisse Geräusch Kulisse.

It's certainly bright, and compact compared with similar bulbs but it is quite noisy due to having a fan in it. I bought it for a kitchen but it was far too noisy so put it in an porch light instead where the noise doesn't matter so much. Too early to tell about its durability.

Bought to replace a mercury vapour yard light. This bulb is twice as bright. Has good warranty.
