17W ( 150 Watt Equivalent ) 4 Pack A21 LED Light Bulb, 2000 Lumens 3000K Soft / Warm White, E26 Medium Screw Base, UL listed, XMprimo

I purchased 2 - 4Paks. The bulbs are fantastic. They are bright, the same color temperature as incandescent bulbs, and come on instantly and save energy. The CFL bulbs take a few minutes to come to full brightness. These are at full light output when you turn on the switch. I have them in lamps that are on my timers and with their long life I don't need to worry about a bulb not working when I am not home. I am now in the process of replacing all my 150 watt bulbs with these LED bulbs from XMPrimo. I will buy 2 more 4 paks.Now XMPrimo's customer service was AWESOME. And I don't use that word lightly. 1 of the bulbs did not work and I returned it and was given a credit back to my Amazon account in hours. Now that's customer service. I am still in shock about how quickly and easily my return was processed.XMPrimo is a great company and they sell a great product.

I have been looking for LED light replacements for my 150 watt bulbs for nearly two years. They did not really exist in A19 or A21 until now!Pros:+ Very bright, 3000k definitely replaces the 150 watt fluorescent bulbs I had+ A21 size fits in most A19 fittings. These bulbs are slightly larger so allow yourself some wiggle room+ Quality seems well made despite being from ChinaAreas for Improvement:- Little pricy even for 4Bottom Line: If you have been waiting for LED bulb equivalents for 150 watt fluorescent, these are a solid buy.

Produce very nice quality light both in intensity and color. Very efficient. I love how cool they are to the touch and don't worry about putting a higher "watt" replacement than the lamp maximum because there's no chance it will melt or catch fire. Nice compact size fits all lamps I have unlike CFLs I've tried at the same "wattage".One complaint: I had a bad bulb that flickered on and off after about a month's use. The other bulbs didn't have this issue so it must have been just 1 bad bulb.

Excellent product, replacing earlier 30 watt CFL lamps and delivering more illumination at almost half the power useage. Perfect answer to CFL slow warm-up during winter weather in my garage/shop, since these LED's come on at very near full briteness and reach full briteness very quickly. Only wish they had a 3500K product, which the CFL's were. May next try their 22 watt LED lamps.

I am disappointed in these bulbs. I bought 4 in Nov. Two failed within weeks and I was given a refund for two bulbs.Now, the other two have failed and they were supposed to last for years.This was for a fixture with an open bottom as seen in the attached photo.I don't know how to reach the company to return the last two bulbs.

Very bright. A little more white that I thought, but I would say that i would buy these again if i needed to.2 bulbs make my whole place bright. I will say you may want to have 4 light points to avoid shadows as these are bright, so the shadows can be dark.

This bulb stopped working today. Upon further inspection I have determined the cause was not the leds themselves. But rather the capacitors on the driving circuitry being insufficiently heat sinked and mounted incorrectly. The led ring is still good.

super bright. used these bulbs installed in floor lamps pointed to the ceiling. Floor lamps were placed in one corner of the room. Our rooms are roughly 10' x 10'. one of these bulbs light the entire room really nice. Color is also a true warm white.
