I have no experience with the double density strips but the hitlights web site says the color temp for both is 6000K so I would expect the to be very close in color. The 300 ct ribbon uses smd5050 led which are brighter than the smd3528 leds on the 600 ct ribbon. I have no way to compare the brightness of the 300 ct vs 600 ct ribbons.

bob, these ecobright led bulbs are manufactured with better quality parts & is designed to last longer with better internal heat dissipation. they are also brighter than the wm led 11w/60w bulb of approximately 800 lumins vs 1100 lumins for the ecobright bulb. these ecobright bulbs are somewhat larger in size too!! neil

(5-smd led lamp / .05 amp x 12volt = .6 watt) ( old incandescent bulb / .25 amp x 12 volt = 3 watts ) The led bulbs look to be as bright as the incandescent bulbs but it is a white light (led) not yellow (incandescent)

Don't know exactly but they seem as bright as the 7 watt Malibu lights. We have a mix of both, and you can't tell the difference except the LED are somewhat less yellow (more white). I've tried a lot of LED replacements, this is very good, no bluish tint. But definitely whiter that incandescent, but not objectionably so.

the 238 is better in the fact that it is LED backlit where the 236 isn't so the 238 is better but only slightly. so it comes down to whether LED is worth the extra $. Other than price and the backlight they are identical.

I was wondering the same thing and still am not 100% sure. But, from what I have read, each 5050 SMD produces 12-15 lumen per chip. This type of strip has 300 chips per 16.4 feet. Check my math, but this comes out to about 219 to 225 lumens per foot of strip. Its hard to find good info on LED strips. No one at Home Depot or Lowes seems very knowledgable. Here is the link where I got my info ... http://www.ledlightsworld.com/led-strips-flexible-led-strips-c-1_49.html

Since they sell a 10 W 900 lumens light for half the price, I presume that the 1800 lumens is for both of them, as together they draw 20 W. (would have been cheaper to purchase two singles though, since one is 30 bucks) see .LEDSTORE 10W CREE High Power LED Work Light Lamp Off Road Bike Motorcycle 2" 30 Degree Spot. Looks similar? There is a nice customer picture with one mounted too.

Maker replied me - it's in 5,000K. It's Kelvin btw. Still no words on lumens though...

Thank you for your question. The listing is accurate. PX05-I36 has been upgraded to four LED lights (2 lights on each side, not in the center anymore). The picture is showing an old version of PX05-I36. New picture will be updated soon.

this desktop one has 420pcs led lamps in total. Usually handheld one has much less lamps.Also, its enery would be stronger and results is better.

This version is the old one with a CREE XM-L led instead of the CREE XM-L2. You can tell by the lumens. The new version puts out 550

Hello,I am sorry we only sell brand high quality brightest SMD LED bulbs(low bright bulbs fats light fades and short lifetime&#65289;,you can use a DC dimmer ,it can dim when use dimmer supply low input voltage ,thanks!

The bright white may be a little brighter than the cool white but they both have a bright white light whereas the warm white has a yellow cast to it. Not sure of the lumen's but I used them to replace the standard bulbs in my motor home and they are brighter and uses less power than my original bulbs. I love these bulbs.

we use the brightest 3528 SMD LEDs for these GRV brand LED Bulns,It about 95~120 Lumens when work at DC12V ~13V ,but Cann't use for more than 13V DC ,maybe become very hot more than 13V and short lifetime,maybe too hot and will Burned soon if input voltage above 14V DC,Someone said Burned out soon due to some new RV output about 14V Voltage,please confirm voltage is about DC12V when install it,thanks!thanks!

It's not a matter of brightness. Both emit the same # of lumens. It's a function of the light spectrum they emit. So it's really an aesthetics question. Some people don't care for "white" that's in the 5,000K range and prefer the "warm" or yellowish light emitted at 3500K.

I am sorry that I, as an ordinary consumer/user, do not have A QUANTATIVE ANSWER for your question. However, by comparing this 'new LED' light bulb to the 4-WATT 'old incandescent' light bulbs we used before, its light output is BRIGHTER AND WHITER. I hope you are satisfied with MY QUALITATIVE ANSWER.
