What's the difference between this roll and the same length that costs $387 at the lighting store and says "High Output"? 42W

Sorry Cynthia, I have not idea what would make that product worth over 30 times the price. Note that you chose the warm white color (2000k). The neutral write (4000k) & the cool white (6000k) each give slightly more light at a cost within pennies.

What's the brand name and model of that $387 version? I cannot compare if I don't have all the pertinent data and specs.

No it isn't. It's too short for your lamp. This one is 18W and the original Arial bulb is 27W. Bulb # is PST27R. It's available on Amazon for around $25.

I do not know the true output i have no way to test but if your worried if the light is not bright don't worry. I have had mine for 8 months now use it on a daily basis is very bright the testing I have seen done on this shows that this light is truly 800+ lumens and I believe it. It's a great deal at 40 bucks I recommend buying 18650 battery and charger I have gone on to buy 3 other lights from thrunite I am very impressed with them all considering I use to work at a outdoor store and sold surefire Phoenix lights and other high end lights. Buy it you won't be disappointed.

My Cree led bulb was bought as a 40 watt equivalent and I believe it is. The packaging states it is a 40 watt equivalent and no mention of 75 watt. It is being used to replace a 60 watt halogen that my wife claimed was too glare y and is a soft light as claimed on the package. My wife is happy with it. Is it possible a a 40 watt version was shipped instead of the 75 watt version or the "AD" had the wrong part number.

I would believe that discrepancy is a typo. This type of light mush use a switch rectifier to convert AC to DC . It can handle 85 -265 V. I just used a photometer (the meter for photographic use) to measure the luminance (roughly means brightness) of this LED at a distance of 1 ft. It has about 4000 lux which can be converted to 4700 lumens. This is way above the nominal value of 2700 lm. I am guessing maybe 2700 lm is an average value during the life span. The LED I measure only a few months old. After 5 to 10 years it might drop to around2700 lm. Hope this helps, more or less.

I shopped for LED bulbs to replace everything in our home. If you shop at the eBay you can find 60 to 100watt equivalents for about $3 to $4 in groups of 10. Local Depot want about four times that. You can also choose between "warm" and "cool" whiteness. It really pays these days to shop China for electronics. If you think your being patriotic by shopping US often you are paying a lot more to pay for profit. VW and Toyota helped the US wake up and produce more quality and efficiency. "Tomorrow and Change" cannot be separated no matter how much you pay, LOL

The one from Home Depot is discontinued, which is likely why the price is so low. Also, those use 14.5 watts while the sylvania's use 10. I purchased 24 of the Sylvania 70734's for my remodel project. I had no lemons out of the box, and when paired with the right dimmer, they are all flicker free through the whole range. If you can find similar reviews for the commercial electric, I would say go for it. If not, then I would suggest going with something that is proven to work effectively and will give you years of use. They will use less power (although not a significant amount) than the commercial electric equivalent. The one from Home Depot is discontinued, which is likely why the price is so low.

Robert I really couldn't find or solve your question in regards to the difference between the 15w & the 25w bulbs's shipping costs. All I can say is the price of this set of 25watt tubular bulbs came with free shipping when I purchased it earlier this year and I think it's a good purchase. I don't dig the "add on" situation whatsoever and I don't know the facts behind it. I just add my items with this quote into my cart and paid out the total costs (with/without free shipping) of my purchases. Wish I can help you better with this matter. Try contacting a seller or even maybe contact Amazon's Help Online to further assist you.

We sell lamps against this listing and the truth is - no they are not made to the same specification as the OEM version. Neither are they likely to last as long. The difference is that the OEM version costs $300+ whilst the compatibles cost $50+. It is also true to say that the quality of compatibles varies from supplier to supplier. We source ours from an ISO9001 accredited manufacturer whilst some of our competitors may not. At the end of the day there is a choice between quality and price and each customer will have different criteria. All our lamps do however, come with a 90 day warranty so it is not a complete gamble.

D.I.Y projects are the best!!!! So happy to be able to share crafts with others. To answer your question I preferUsing a 40-60 watt regular light bulb (soft) I hope you have a great experience with your project. Good Luck

FYI - A 40W light bulb is about 450 lm, so a 55 lm source would be about 1/8th as intense as a 40W bulb.

The Amazon web ad says each 5 meter strip consumes 24 watts. When I received the L.E.D. strips the info said they consume 36 watts. I would go with the 36 watts and since the power supply output is 100 watts you would need one power supply for every two strips. I have noticed if the strips are wired in series the first L.E.D. is much brighter than the last. I am using these strips for under counter lighting with 2 cabinets on the north and 3 on the south. The north lights are brighter than the south. Then the lights on the south are brighter on the feed end and dimmer at the far end. Hope this helps.

No idea. It's 13W, and I looked for one for years. Was SO tickled to find it, for my little Ott light was going to waste. It's a pleasant bright. Hope that helps.
