MR16 LOW VOLTAGE LED BULBS

36 LED - Warm White and Cool white: The 36 LED unit available in cool white and warm white is as far as we can go with standard 5 mm LED. Nowadays we pump them up to 20,000 MCD per LED but they can't compare to halogen output and viewing angle. These can be used in hallways and areas where you need a spotlight effect. Even though we make the LEDs protrude from the rim of the reflector, providing some decent side light, they still are more of a spotlight than a floodlight.

Single 3 W diodes - Warm White and Cool White: 60° viewing angle - comparable to 20w halogen.

The Cool White 3w units are currently available in the O-Type which are being phased out in late May 2008. The higher BIN quality T-Type are being introduced June 2008. They are currently available and you can ask for these by preference in an e-mail to us. They will be $3 more expensive than current O-Type units but they produce 15% more light and will maintain their lumens output a lot longer.

The Warm White single 3 W units are from Nichia in South Korea - we have found their Warm White to be of excellent colour consistency and we have seen no fading. By nature they aren't quite as bright as the Cool White because of the colour temperature but they do make up for it in ambience.

3x1w units available in Warm White and Cool White - 120° viewing angle - comparable to roughly 35 W halogen.

By far the best MR16 we've produced - these also incorporate thermal cutout just in case they get too hot, make sure you never put installation or any other materials close to the fitting because these need to breathe. Not as bright as a 50 W halogen unit they will use 1/5 the power of a halogen bulb the same size (roughly 35 W)

"Can I use 240v AC/12v AC transformers with these bulbs?"

Yes - although only with the iron core transformers, they will not operate properly with electronic transformers.
Electronic transformers are looking for a constant high load and will flicker from continuous start-up and shutdown.
Rectifiers are built into all our AC capable bulbs, this brings the current back to DC as LED's themselves are DC driven.
Given the choice - we advise our customers to run these bulbs on DC only.
Our new 240vAC~14vDC power supply has a 14 vDC output.
This this allows for long cable runs of a standard house without affecting the voltage getting to the bulb.
Keep in mind that the new 3w and 3x1w MR16 units are 8~15v DC - this gives greater ability to withstand voltage drop anyway.
The LED bulbs that we stock have small bridge rectifiers inside (this converts the 12v AC power to DC)

"How bright are your 8~15v DC 3w 10 degree bike lights?

The 10 degree spotlight when measured directly in front will rival a 40w halogen - we must qualify that by saying it will rapidly fade after that narrow spot beam - it's a spotlight - much like a torch.
We now have 3x1w 25° units in stock as of late May and will be on the website hopefully by the 20th of May. They are currently available and please contact if you require these before they come up on the website.

"What is the difference between the 5500k and 3000k color range?"

The 5500k colour is about as close to neutral light as we can get - daylight being about 5800k - anything after that and you start getting that blue tinge which is actually called daylight. The amber usually are at about 2000~3000k with Warm White being in the 4000 K. zone. Cool White then take it up to about 5500 K. with daylight starting to cut in and taking it all the way to 7000 K. in comfortable viewing White range.
Most of the early white 5mm LED lights had that blue tinge because they actually were a blue LED with some doping phosphors added - as they aged they got more blue because it was the doping phosphors breaking down not the blue chip itself.

"Can you dim MR16 LED bulbs?"
Our LED bulbs are current driven - dimmer type voltage variations wont affect them.
To dim an LED bulb you would need a current based dimmer.
These are called pulse modulators - these devices keep the voltage stable whist switching the current on and off millions of times per second.
By adjusting the pulse rate (or gap) - this creates a dimming effect and causes no lasting problems for the LED bulb.
Commercially available? Not yet - as of July 2008.

Why don't you sell LED deck lights?

With regard to recessed deck lights there are several types available these days but we highly recommend that if you are going to use a recess on deck light then you would need the type that has a replaceable bulb.
We've seen many LED deck lights that are one unit, the LEDs are actually sealed inside the fitting.
We don't like this type of idea because our experience has been that LEDs fail sometimes and often when LED bulbs fail only a couple of LEDs will actually stop working but this doesn't look very good and renders the bulb defective.
We've seen this many times and we see an even more so where there aren't enough quality controls over the production of the LEDs.
The company putting together the fitting will obtain their LEDs from any particular area.
We sell LED bulbs that have passed all the regulation standards and we highly recommend that if you are going to get any LED lights in the future make sure that the fitting can take a replaceable bulb.
The most common type of replaceable fittings are MR 16, these are the common recess downlights that you see in houses and garden fittings.

MR16 - 36 LED Warm White and Cool White

We use 20,000 MCD LED and incorporate a wide 8~30vDC operating range in these. They tend to have a spotlight effect and are for use in narrow areas. The LEDs do protrude past the rim of the reflector however and quite a lot of light is thrown off to the side. If you have a small tent it would generally light the tent although throwing about a 1 to 1 1/2 metre circle on the table.

MR16 - High power 3w and 3x1w

We've been through several versions of the 3 W unit over the years firstly using Luxeonics for our initial production runs but quickly moving to the Cree Company. Cree have developed the T-type unit recently and we have moved to that as it is superior in lumens maintenance and brightness to the O-Type. When you are pricing units from LED suppliers please ask them for the BIN quality of the bulb they supply. Try to make sure it is T-Type unit not an O-Type unit. With both the single 3 W unit and a 3x1w units we always use the T-Type from Cree now.

MR16 3 watt bike light 10 degree ( New MR16 25° T-Type from Cree now available)

We did quite a lot of research on what our new MR16 bike light might be based on customer feedback.
Firstly our experiences with single 5 W units have not been really good in the MR16 footprint.
We started out Luxeon units back in 2004 but slowly moved to Cree's diodes.
Testing of 5w diodes from Cree was excellent in performance but they thermally cut out after about 20 minutes.
Testing combinations of 1w diodes yielded higher performance lumens per watt with no thermal cut-out under normal room temperature conditions.
So we moved all our MR16 GU10 E27 and B22 to this type (3x1w)
This did present some problems with the bike light however - we can't collimate (or narrow) the beam down to 10° using 3x1w units the best we can do is 25°.
It does have a bright spot in the middle on test and we think now this is probably as best as we could have done.

It will therefore have a 210 lm output with roughly 5 W consumption in total - the most efficient that LED can be right now.

MR11 1- 3 watt

What's about that label '1-3 Watt' for the MR11 light?

Sometimes with electronics it's damned if you do and damned if you don't !
When we first introduced the MR11 unit we stated the unit as being a 1w diode and quoted the lumens figures accordingly.
But when customers put them on a meter the bulb was consuming nearly 3 W (actually about 2.7 W) because of the electronics involved so we actually called the unit an MR16 or MR11 3w unit because that is what it actually consumes.
We then left it up to the customer if they were satisfied with the light output at 3w consumption.

So sorry that looks like it's deceptive it's really not, it's in the customer's favour more so than ours.
The lumens figures we quote for 3 Watt total consumption of the bulb more so than many rated wattage consumption of the diode without the electronics.

The speaker placed on the back of the bulb and the labelling on the box represents the wattage consumption of the diode and is in a sense the model number of the diode, not the actual consumption of the bulb.
What I think we will do is amend the descriptions on the MR11 Cree and Nichia 3w diodes to have mention of the 1w model.

LED light dome

How do I attach the Light dome ?

The mounting screws are situated around the outside of the dome light so it can be easily screwed to a flat surface from above.
The cover of the unit is screwed to the base so that the screw goes through both cover and base to give a more secure connection.

100 to 240vAC TO 12v (14.4vDC) power supply - 18w max (15w optimal)

The new switching adaptor (lso called transformer, or power supply) works in a input voltage range from 100 to 240 volt and is suited for both the US and Australian type mains power supplies. We produced this particular power supply with a 14.4vDC output so that it would be capable of long cable runs in gardens for example.

How many LED lights can I run from one power supply?"
The transformer is capable of delivering 18 watts but it is recommended to use 15 watts for continious usage.we will be able to tell you how many power supplies you need if you send us an e-mail.
"What is the maximum cable run distance from switching adaptor to lightbar with the normal cable?"
Once again it would be best for us to assess each situation independently as there are so many variables. We have successfully achieved garden runs of 50 m at 15w.

LED mood candles (single white candle with AA batteries!)

The ON/OFF switch is on the bottom of the candle - so is the battery compartmet latch.

These LED candles look like real candles and when lit up only the 'wick' flickers - the body of the candle stays unlit just like a real candle.
The candles go inside the silicon holders and the wick lights up and shines through.
Do not pull off the white cap - that is the 'wick'!!

"Does the candle come out of the glass for battery replacement?"
Yes - but it won't be neccessary - the battery compartment is at the base of the candle and the ON / OFF switch too
